Integrated circuit amplifier arrangements |
摘要 |
In a differential amplifier having a pair of emitter follower outputs, power saving is obtained by switching the pull-down currents so that the emitter followers have to provide current to drive the load only in the on direction. The preceding stage is a cascode stage, so that the switching signals for switching the pull-down currents may be derived from the emitter circuits of the cascode stage output transistors.
