摘要
A transimpedance amplifier based on InGaP/GaAs HBTs have been developed and realized. It is applicable for bit rates of 10Gbps. The cascode structure is applied for its high gain and bandwidth. The chip size of fabricated transimpedance amplifier is 1.5 x 1.5mm(2). The measurement result showed transimpedance gain of 41 dB Omega and a -3 dB bandwidth of 6.7GHz. The output reflection coefficient is better than -9 dB over the bandwidth of operation.
