摘要

This paper presents a low temperature coefficient (TC) CMOS BGR for high-performance multi-channel analog-to-digital converter (ADC) working under wide temperature range. Besides the logarithmic compensation, both leakage and piecewise curvature compensation are implemented to extend its operating temperature range and keep its low TC. A β-compensation technique is used to cancel the PTAT and non-...
