Abstract
A pipelined data converter current biasing system employs a frequency-to-voltage converter (FVC) operational to convert a plurality of desired sampling frequencies to a plurality of output voltages and a voltage-to-current (V to I) converter operational to convert the plurality of output voltages to a plurality of bias currents. The plurality of bias currents function to bias the data converter operational amplifiers such that the data converter power consumption is dependent on the plurality of sampling frequencies in a way that optimizes power consumed by the data converter with respect to the sampling frequency.
