A wideband integrated circuit amplifier for fixed-gain application

  • 50 Accesses

  • 7 Citations


Circuits which achieve precise gains without the use of negative feedback are of interest because of their simplicity and potential for achieving large bandwidths. A circuit architecture based upon precision current mirrors for producing fixed gains without the use of feedback has been reported in the literature and implemented on a BiCMOS process [1]. This paper provides further analysis of this approach and applies it to a new bipolar amplifier, intended for such applications as real-time active filter synthesis.
