초록/요약
This paper presents a novel symmetric current-conveyor transimpedance amplifier (SCC-TIA) implemented in a 0.13-mu m CMOS technology for the applications of LiDAR systems, where a modified-cascode configuration is newly proposed for input current buffer to deliver the photo-currents to the following voltage-mode inverter TIA without signal loss. Measured results of the proposed SCC-TIA demonstrate 69-dB Omega transimpedance gain, 410-MHz bandwidth, 13-pA/sqrt (Hz) average noise current spectral density, and 20-mW power dissipation from a single 1.2-V supply. Chip core occupies the area of 280 x 130 mu m(2).
