ABSTRACT:
I describe and claim an improved digital-to-analog conversion device and method. The device comprises a current supply circuit to generate a plurality of control currents responsive to a plurality of digital signals. An input voltage generating circuit is adapted to generate a plurality of input voltages responsive to the digital signals and the control currents. And a plurality of operational amplifiers is adapted to output a plurality of analog signals responsive to the input voltages.
