62 10 4 gain of the amplifier when the tia has 10 kωfeedback resistor.

Lidar receiver circuit. At the end an electronic photonic integrated circuit for a micro imaging fmcw lidar is presented as an example. Comparison of ipda lidar receiver sensitivity for coherent detection and for direct detection using sine wave and pulsed modulation xiaoli sun1 and james b. Mao ye s 14 research works with 6 citations and 1 044 reads including. Popular lidar architectures and circuits are presented and the superiority of the fmcw lidar is discussed in terms of range resolution receiver sensitivity and compatibility with emerging technologies.

The amplifier s fast overload recovery makes it ideal for lidar receivers. The sensitivity of a ladar receiver depends in equal measure upon each of these components. These lidar receivers are available in high speed single element linear array and area arrays configured with low noise amplifiers and readout integrated circuits roics. This transimpedance amplifier offers 74kohm transimpedance gain and 30µa linear input current range.
