An apparatus for implementing a front end core for a transimpedance amplifier includes an input transimpedance stage that receives an FE core input signal and responsively generates an output transimpedance gain signal. A first output gain stage receives the output transimpedance gain signal and responsively generates an FE core output signal. A phase inverter stage also receives the output transimpedance gain signal and responsively generates an inverted output signal. A second output gain stage then receives the inverted output signal and responsively generates an inverted FE core output signal.
