#100daysamplifierdesign #100daysamplifierdesign Day13 The emitter (or source) degeneration resistor is crucial in stabilizing the gain of a transistor amplifier. This resistor, placed in series with the emitter (or source), provides negative feedback that helps to stabilize the operating point and make the gain less sensitive to variations in temperature and transistor parameters. The resistor works by increasing the voltage drop across it as the emitter (or source) current increases. This increase in voltage drop reduces the base-emitter (or gate-source) voltage, which in turn reduces the current through the transistor, counteracting the initial increase. This feedback mechanism helps to stabilize the gain. It is called "degeneration" because the resistor partially counters the transistor's amplification, effectively reducing (or degenerating) the gain. Despite this reduction, the stability it provides is highly beneficial, making the amplifier's performance more consistent and reliable across varying conditions.

This post is an abridged copy of a Toshiba application note. In my humble opinion,  the original document and this post include many inaccuracies and errors. The biggest one being the shape of the diode voltage during and after the reverse recovery duration. The reverse recovery process is initiated by a reversal of the diode voltage so after the reverse recovery ends the diode voltage is the imposed negative voltage and not zero as seen in the figure. An explanation of the diode reverse recovery process and its implications can be found in  https://lnkd.in/ebZ8WQhb

Do you know the alternative to traditional transistors is the memristor. A memristor is a non-volatile two-terminal electrical component that maintains a changing state based on the flow of electric charge. It has properties that make it a potential alternative for certain applications in memory and processing. Also to keep in mind that while memristors show promise, they are not a direct replacement for all transistor functions.

Lithium-Ion battery's introduce: Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ is embedded and de-embedded between the two electrodes: when charging, Li+ is de-embedded from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true.
