ABSTRACT:
A circuit for limiting transient intermodulation distortion in a amplifier system including an operational amplifier having a gain stage and a feedback network connected between the gain stage and the amplifier feedback port together with a pair of oppositely poled diodes, connected in parallel and coupled by means of capacitors between the amplifier output port and feedback port to limit the operational amplifier going to the supply rails under non-linear conditions thereby reducing the slew rate recovery time and therefore the amount of transient intermodulation distortion.
