On-chip Temperature Compensation with a Reference Voltage Method for CMOS Image Sensors

This thesis presents a temperature-dependent reference control method to compensate for the temperature effect on CMOS image sensors from -40◦C to 125◦C. Recently, machine vision has been one of the most important applications for CMOS image sensors. However, the working environment and operation might generate large temperature variations and...

A CMOS Temperature Compensated Log-Amp Detector

Publications of bipolar log-amp detectors for RF power detection show good temperature and RF performance. So far published CMOS log-amps fail to demonstrate accurate performance over temperature. This thesis present a temperature compensated CMOS RF power detector based on the log-amp architecture with an industry temperature range of -40 C to...
