If the base current varies, so does the output current, which is how a transistor functions as an amplifier. It’s similar to the way you control the flow of water with a faucet. With a small ...

The amplifier is a very old-fashioned, single-ended design with an output transformer. The transistors in question are the now-archaic germanium PNP devices that had probably already been ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables” was published by University Minnesota and Cadence. “Device ...
