ABSTRACT:
A circuit includes a digital-to-analog converter configured to produce an analog output signal (1) proportional to a reference signal and (2) as a function of a digital input signal. The converter comprises a plurality of non-trivially complex admittances configured so that each non-trivially complex admittance can be selectively switched as a function of the digital input signal so as to be coupled between a reference terminal configured to receive a reference signal and an output terminal. The method comprises selectively switching non-trivially complex admittances as a function of the digital signal between a reference terminal and an output terminal.
