ABSTRACT:
A wideband, constant-gain voltage amplifier. An input transistor has a transconductance that is a function of temperature and fabrication process. A transimpedance amplifier is connected to the input transistor. The transimpedance amplifier has a transimpedance that is a function of temperature and process that is substantially the inverse of the function of temperature and fabrication process of the transconductance of the input transistor.
