Building a power hi-fi amplifier with MOS transistors requires the implementation of a relatively large number of components because, at the level of power stages, the connection between the bipolar transistors that make up the input stages and the MOS transistors of the output stages is far from simple. Fortunately, there is an elegant solution […]

Power Amplifier Circuit using IC 741 and MOSFET
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 […]
