Patent abstract

Reference network embodiments are disclosed that provide reference signals to, for example, switched-capacitor multiplying digital-to-analog converters (MDACs) in pipelined analog-to-digital converters (ADCs). These embodiments are configured to maintain accuracy of the levels of the reference signals in the presence of high speed charge-injection and charge-extraction currents which are presented by the MDACs.
