Abstract
Techniques for improving a power supply accuracy of a precision data converter system, such as analog-to-digital converter circuits (ADCs) and digital-to-analog converter circuits (DACs). Improving the power supply accuracy can enable a reference voltage to be as large as possible, thereby increasing the signal-to-noise-ratio (SNR). The techniques can also simplify power supply sequencing requirements for the data converter system.
