Abstract

This paper presents a post layout simulation results of a 117 dBΩ gain, 20 MHz bandwidth and 7.2 nArms total integrated input referred noise optical receiver for the Near Infrared Spectroscopy (NIRS). The chip is optimized for long battery life time operation with a 2.35 mW total power consumption. An Automatic Gain Control (AGC) is presented to extend the maximum overloading input current of the chip. The chip can operate at an input current of 6.4 µAp-p with less than 1% Total Harmonic Distortion (THD) at the output. The optical receiver is optimized for 2 pF off-chip photodiode.
