초록/요약
A multi-channel CMOS transimpedance amplifier(TIA) array is realized in a 0.18-μm CMOS technology for the applications of panoramic scan LADAR systems. Each channel consists of a PIN photodiode and a feed-forward TIA that exploits an inverter input stage followed by a feed-forward common-source amplifier so as to achieve lower noise and higher gain than a conventional voltage-mode inverter TIA. Measured results demonstrate that each channel achieves 76-dBΩ transimpedance gain, 720-MHz bandwidth, and -20.5-dBm sensitivity for 10-9 BER. Also, a single channel dissipates the power dissipation of 30 mW from a single 1.8-V supply, and shows less than -33-dB crosstalk between adjacent channels. © The Korean Institute of Electrical Engineers.
