1-Gb/s Readout Amplifier Array for Panoramic Scan LADAR Systems Kim, Dayeong; Park, Sung Min;
In this paper, a dual-channel readout amplifier array is realized in a standard 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 transimpedance gain, 829 MHz bandwidth, -22 dBm sensitivity for , -34 dB crosstalk between adjacent channels, and 45 mW power dissipation from a single 1.8 V supply.
