Hello, dear Connections! I’m excited to present one of my recent endeavors in analog layout: the Comparator. This sub-block plays a crucial role in flashADC design. Here are few key highlights from the design and layout process: 1.Protection and Symmetry: We incorporated dummy devices to safeguard critical components. Our routing design ensures symmetry throughout. 2.PR Boundary and Pin Placement: We’re adding a PR (Place and Route) boundary, with pins strategically positioned at the boundary edges. 3.Guardring Separation: To address different potentials, we’ve separated guardrings for the current mirror and PMOS differential pair in the preamp. 4.Via Optimization: Multiple vias enhance guardring effectiveness by minimizing resistance. 5.Power Pin Placement: Placing power pins at corners optimizes power distribution. 6.Comparator Guard Ring: The entire comparator circuit resides within a single guard ring (PTAP). 7.Matching Techniques: Employed Interdigitization matching for PMOS and NMOS current mirror circuits and common centroid matching for differential pair circuits. 8.Layout Optimization: We’ve positioned the inverter block on the right side to streamline routing. 9.Iref_snk Dummy Device: A dummy device was added for the single component with input Iref_snk. 10.Wider Power tracks (VDD and VSS): To enhance drive strength. 11.Successfully cleared DRC and LVS checks. This project has significantly enhanced my expertise in analog layout and design. I’m truly appreciative of this valuable opportunity at Epitome Circuits Suman Hallur. #analoglayout #comparator #analogdesign #fresher #opentowork #Semiconductor

What about length matching? (next step is dedicating layers to GND planes for 50o impedance). Some call this art. Is it? #StreetPlug #PCB #design #embedded #engineering #altium

👃That New #PCB Stencil Smell Gets Me Evertime!!! It's always exciting and a little anxiety inducing to get new Fabs in and a Stencil for your newest design. The "Is it going to work or not" thoughts constantly run through my mind as I'm putting together the first prototypes of a design. What about you? #electronics #design #engineering #diy #engineer

A few PCB designs are not just technical projects; they become close to our hearts. Some designs challenge us, push our limits, and ultimately make us proud. These aren't just circuits on a board; they embody innovation, creativity, and a relentless pursuit of excellence. When a PCB design project becomes more than just a job, it turns into a passion project. The late nights, the problem-solving, and the countless iterations all pay off when we see our ideas come to life. It’s a reminder of why we do what we do – for the love of technology and the satisfaction of creating something truly remarkable. Here’s to all the crazy, challenging, and near-to-the-heart PCB designs that make our work so rewarding! #PCBDesign #Engineering #Innovation #PassionProject #Electronics

Hello everyone!  I'm excited to present the details of my recent Analog layout project, which focuses on crafting the design of an Operational Amplifier (Op-amp): 1. The Op-amp architecture includes various elements like PMOS and NMOS current mirrors, NMOS differential pairs, and output stages with PMOS and NMOS biased by current mirrors. 2. Precision matching techniques were consistently applied, incorporating interdigitation matching for PMOS and NMOS current mirrors and common centroid matching for NMOS differential pairs. 3. Guard rings were strategically implemented to prevent latch-up issues. 4. Critical signal paths, such as Vin- and Vin+ in the differential pair, were shielded with side-wall shielding to minimize interference. 5. Dummy devices were strategically included to ensure active devices are safeguarded against process variations. 6. Power tracks (VDD & VSS) were meticulously designed with wider metals to enhance their drive strength. 7. Careful attention was given to minimize layout area while adhering to minimum Design Rule Check (DRC) rules and optimizing metal orientations. 8. The design underwent comprehensive verification utilizing DRC and Layout Versus Schematic (LVS) checks. Thank you Suman Hallur for the opportunity to work on this project, which has significantly enhanced my expertise in analog layout design. #analoglayout #fresher #semiconductor #layoutdesign #opentowork #highspeed #electronics #lvs #drc

🤔 Have you ever thought about how important power is in our lives? 💡 Not just the kind that lights up our homes, but the power that lets people do things, make decisions, and influence others. 💪 Power is like the invisible force that helps shape everything around us, from who gets to be in charge to how we work together in society. 🔌 Just like how power plays a crucial role in our daily lives, it's equally important in PCB design. 🔋 Ensuring the integrity of power within these circuits is a key aspect that cannot be overlooked. 🛠️ So, power integrity analysis in PCB design is all about making sure that the power flowing across the circuit board stays steady and reliable. 💡 It's like keeping a consistent flow of electricity to prevent any hiccups that could mess with the performance of the components. 🚀 Let's say you're working on a high-speed digital design. 🔄 Power integrity analysis ensures that the power distribution network can handle the rapid switching of multiple components without causing voltage drops or noise that could mess up the signal quality. 🔧 It's kind of like maintaining a smooth, uninterrupted flow of energy throughout the whole system. 🔍 In this exploration, we will delve into seven pervasive myths about power integrity analysis in PCB design, based on our findings from design analysis. 🔬 By dissecting these myths with a technical lens, we aim to illuminate the true principles of power integrity, empowering designers to navigate this complex terrain with confidence and precision. 🚀 Ready, set, go! https://lnkd.in/gtkGgeUY #powerintegrity #poweranalysis #pcbdesign #electronics #circuitanalysis #signalquality #voltagedrops

🤖🧑🏻💻🛠 Essential PCB Design Tips for Success 1. Plan Your Layout: Start with a clear schematic and plan your component placement strategically. Keep related components close to minimize trace lengths and reduce noise. 2. Prioritize Signal Integrity: Maintain consistent trace widths, avoid sharp angles, and use proper grounding techniques to ensure clean signal transmission, especially in high-frequency circuits. 3. Power Supply Decoupling: Place decoupling capacitors close to power pins of ICs to filter out noise and stabilize the power supply. 4. Minimize Crosstalk: Keep signal traces that run in parallel at a distance or add a ground trace between them to prevent interference. 5. Optimize Trace Width: Use appropriate trace widths for different current-carrying paths. Thicker traces for high-current paths reduce resistance and heat generation. 6. Ground Plane Strategy: Use a solid ground plane to reduce electromagnetic interference (EMI) and provide a low-impedance return path for signals. 7. Thermal Management: Design with heat dissipation in mind. Use thermal vias, heat sinks, and copper pours to manage heat in high-power components. 8. DRC Compliance: Always run a Design Rule Check (DRC) before finalizing your PCB. It helps catch potential issues like trace spacing violations or unconnected nets. 9. Label Components: Clearly label all components and connectors on the silkscreen layer for easy assembly and troubleshooting. 10. Test Points: Include test points for critical signals and power rails. This makes debugging and testing easier after production. 🔌 Good design is key to reliable hardware. Keep these tips in mind for your next project! #pcb #circuit #electronicsengineering #pcbdesigning #kicad #eda #tinkering #electricalengineering
