WebMar 17, 2024 · The transistor is also what makes amplifiers work. Instead of having just two states (ON/OFF) it can also be anywhere in between “fully on” and “fully off”. That means a small signal with almost no energy can control a transistor to create a much stronger copy of that signal in the collector-emitter (or drain-source) part of the transistor. WebThe differential amplifier can be implemented with BJTs or MOSFETs. A differential amplifier multiplies the voltage difference between two inputs (Vin+ - Vin-) by some constant factor Ad, the differential gain. It may have …
