Differential amplifier for high frequency amplification at low voltage, has input stage coupled to load circuit with features for dynamic compensation

摘要

The full differential amplifier (24) has a pair of input transistors (12A,B) coupled to gating transistors (14A,B). Included is a load circuit consisting of transistor pairs (16A,B) and a second pair (20A,B) operating in the saturation region. For tuning and compensation there are capacitors (22A,B).
