Abstract
The output signal from the TIA is in the range of a few millivolts and more gain is needed to reach at least an amplitude of 200 mV required by the decision circuit. This additional gain will be introduced by the post amplifiers (PA) following the TIA. As stated in Chap. 6 the TIA specifications determine the performance of the optical receiver, such as the sensitivity and the dynamic range. The PA specifications have less impact, but insufficient PA bandwidth, gain, and sensitivity can degrade the optical receiver’s overall performance. The effect of the PA specifications should be considered to achieve the required optical receiver performance (gain, bandwidth, sensitivity, dynamic range, ...) at minimum or reasonable power consumption.
