MICROSTRUCTURE ENHANCED ABSORPTION PHOTOSENSITIVE DEVICES
Microstructures of micro and/or nano holes on one or more surfaces enhance photodetector optical sensitivity. Arrangements such as a CMOS Image Sensor (CIS) as an imaging LIDAR using a high speed photodetector array wafer of Si, Ge, a Ge alloy on SI and/or Si on Ge on Si, and a wafer of CMOS Logic Processor (CLP) ib Si fi signal amplification, processing and/or transmission can be stacked for electrical interaction. The wafers can be fabricated separately and then stacked or can be regions of the same monolithic chip. The image can be a time-of-flight image. Bayer arrays can be enhanced with microstructure holes. Pixels can be photodiodes, avalanche photodiodes, single photon avalanche photodiodes and phototransistors on the same array and can be Ge or Si pixels. The array can be of high speed photodetectors with data rates of 56 Gigabits per second, Gbps, or more per photodetector.

Method and system for process and temperature compensation in a transimpedance amplifier using a dual replica
The present disclosure provides for process and temperature compensation in a transimpedance amplifier (TIA) using a dual replica via monitoring an output of a first TIA (transimpedance amplifier) and a second TIA; configuring a first gain level of the first TIA based on a feedback resistance and a reference current applied at an input to the first TIA; configuring a second gain level of the second TIA and a third TIA based on a control voltage; and amplifying a received electrical current to generate an output voltage using the third TIA according to the second gain level. In some embodiments, one or both of the second TIA and the third TIA include a configurable feedback impedance used in compensating for changes in the second gain level due to a temperature of the respective second or third TIA via the configurable feedback impedance of the respective second or third TIA.
