Abstract
A wide bandwidth push-pull parallel amplifier cicuit is provided that includes a main amplifier stage and a parallel stage comprising a transimpedance amplifier and a follower circuit. Both amplifier stage inputs are coupled to the amplifier circuit's input terminals. The output from the main amplifier stage is coupled to the input of the follower circuit. The output of the follower is summed with the output of the transimpedance amplifier to provide a voltage output. The gain bandwidth product of the amplifier circuit is improved beyond that of a single stage while maintaining the delay of a single stage.
