Abstract
In this paper, a dual-channel readout amplifier array is realized in a standard $\small{0.18{\mu}m}$ CMOS technology for the applications of panoramic scan LADAR systems. Each channel consists of a PIN photodiode with 0.9 A/W responsivity and a 1.0 Gb/s readout amplifier(ROA). The proposed ROA shares the basic configuration of the previously reported feedforward TIA, except that it exploits a replica input to exclude a low pass filter(LPF), thus reducing chip area and improving integration level, and to efficiently reject common-mode noises. Measured results demonstrate that each channel achieves $\small{70dB{\Omega}}$ transimpedance gain, 829 MHz bandwidth, -22 dBm sensitivity for $\small{10^{-9}BER}$, -34 dB crosstalk between adjacent channels, and 45 mW power dissipation from a single 1.8 V supply.
