ABSTRACT:
An amplifier having an input stage with inverting and non-inverting input terminals, a voltage amplifier stage with relay terminals and being operatively connected to the input stage, a SEPP output stage with transistors and an output terminal, and a constant-current bias circuit between the relay terminals for absorbing current bypassing between the relay terminals. The transistors are connected to the output terminal via resistors. The constant-current bias circuit is free of being in direct connection with the output terminal. The amplifier is incorporated in place of an emitter follower in a compact disc player or laser video player and may be incorporated into a driver of a loudspeaker, a magneto-optical recording system or a magnetic disc system for mass storage.
