ABSTRACT:
An output stage for an amplifier operating under capacitive loading conditions includes an FET-bipolar composite connected between its input and its output and an emitter follower connected in parallel with the FET. A current source and current tracking circuit maintains the emitter follower conductive at all times, such that relatively high frequency input signals are supplied to the output through the emitter follower. When the output stage is sourcing current to the load, the signal path is through the emitter follower. When the output stage is sinking current from the load, the signal path is primarily through the FET when relatively low frequency input signals are connected thereto and the signal path is primarily through the emitter follower when relatively high frequency input signals are connected thereto.
