A 4-Channel 12-Bit High-Voltage Radiation-Hardened Digital-to-Analog Converter for Low Orbit Satellite Applications.

This paper presents a circuit design and an implementation of a four-channel 12-bit digital-to-analog converter (DAC) with high-voltage operation and radiation-tolerant attribute using a specific CSMC H8312 0.5-μm Bi-CMOS technology to achieve the functionality across a wide-temperature range from -55 °C to 125 °C. In this paper, an R-2R resistor network is adopted in the DAC to provide necessary ...
