A four-channel transimpedance amplifier array is realized in a 0.8μm Si/SiGe HBT technology for parallel optical interconnect applications. Measured results demonstrate that each channel provides the bandwidth of 3.9GHz, the transimpedance gain of 62dBΩ, and the average noise current spectral density of 7.5 pA/ √Hz. The array achieves less than -25dB crosstalk between adjacent channels and dissipates 40mW in total from ±2.5V supply.
