ABSTRACT:
The present disclosure relates to a push-pull transimpedance amplifier (TIA) that receives a push-pull radio frequency (RF) input current signal having a push current and a pull current and includes a common-emitter pre-amplifier and a dynamic feedback current source (DFCS). The common-emitter pre-amplifier receives at least a portion of the push current and provides a first RF signal based on amplifying the push-pull RF input current signal. The DFCS provides at least a portion of the pull current based on the first RF signal. The push-pull TIA may operate at high data rates, may have high input sensitivity, may provide linear amplification of the push-pull RF input current signal, or any combination thereof. The push-pull TIA may provide an RF output signal based on amplifying the push-pull RF input current signal.
