A CMOS Transimpedance Amplifier Accommodating Wide C<sub>PD</sub> and Input Bias Range for Chaos Lidar
This paper presents an input bias-adjustable and large-capacitance-tolerance transimpedance amplifier (TIA) for a chaotic light detection and ranging (Lidar) system. To cover the APD-bias adjustable range of $\pm 0.5 \mathrm{~V}$, a dual supply of 3.3/1.0 V that consumes $\mathbf{2. 5 / 1. 8 ~ m A}$ is used. In the $\mathbf{9 0 - n m}$ CMOS process, the TIA shows the $\mathbf{6 0 - \mathrm { dB } \Omega}$ gain and 450-MHz bandwidth. Its input-referred noise (IRN) is $61.3 \mathrm{pA} / \sqrt{\mathrm{Hz}}$. This amplifier has been integrated into the prototyping system to generate the depth image with high detection accuracy.
