ABSTRACT:
An apparatus and method is provided that improves the dynamic range of an optical transimpedance receiver. The receiver includes a photodetector, a transimpedance front end amplifier and a non-liner feedback. The non-linear feedback means consists of a Schottky diode and shunting the transimpedance resistor with a parasitic capacitor. A lead compensation network is further included in the feedback circuitry to provide stability to the non-linear circuit by advancing the phase shifting of the transimpedance front end by 45 degrees. By stabilizing the frequency off the circuit, the dynamic range is increased from 26.6 dB to 40 dB.
