An amplifier having output transistors with collector-to-emitter paths connected in series for application of operating potential and connected in push-pull for signal, is afforded over-current protection by limiting the sum of the base currents available to the output transistors. This sum current ...
The push pull amplifier is a power amplifier and is frequently used in the output stages of electronic circuits. It is employed whenever high output at high efficiency is required. The audio power amplifiers used in transistor receivers, tape recorders, record-players, public address systems etc. ...
