On the optimum design of the front-end PIN-heterojunction bipolar transistor optoelectronic integrated circuit photoreceiver

In this article, a detailed analysis of the performance of an integrated front-end PIN-heterojunction bipolar transistor photoreceiver has been given and optimum designs are suggested for maximum gain-bandwidth product (GB) and gain-bandwidth-sensitivity measure (GBS) of the device. The present SPICE-based analysis requires the equivalent circuit model of the receiver components. An expression for the impulse response of a PIN photodiode in the …
