Current Mirrors and Long Tailed Pairs

Differential Amplifiers – what they do  (Part One) Long tail pairs or differential amplifiers have one important purpose:  To amplify the difference between two inputs or act as a switch. In a perfect case the voltage gain of the differential amplifier is the product of the differential gain or Ad and (Vin+  subtract Vin-). In … Continue reading Current Mirrors and Long Tailed Pairs
