Abstract

A Sensor Control Chip (SCC) that can drive a 20 V adj ustable output voltage swing and a maximum output current of 100 rnA has been developed to provide the required clock and bias signals for the Large Synoptic Survey Telescope's CCD imagers. The prototype chip has been fabricated in a 0.8-lJ.m BCD-SOl process, and is designed to operate down to 175K. The circuit consists of current steering DACs followed by transimpedence operational amplifiers to control the rail voltages of the clock signals and bias voltages. The clocks are input to the SCC through LVDS receivers and converted internally to the required amplitude for driving the CCD. Design techniques will be presented along with room temperature and operational temperature test results obtained from prototype chips.
