In this post we study a power amplifier design configured using an ordinary IC 741 and a couple of MOSFETs. An operational amplifier’s output power such as from an IC 741 can be typically enhanced when a complementary emitter follower transistor is coupled at its output. The same could also generally be accomplished using a […]
