High gain amplifier using two current mirrors |
摘要 |
An op amp is disclosed in which a high-gain differential input stage drives a high-gain common emitter stage that in turn drives an emitter follower buffer output stage. Adequate voltage gain is obtained in only two stages which makes the amplifier easy to compensate and much less subject to spurious oscillation.
