Error cancellation in a current digital-to-analog converter of a continuous-time sigma-delta modulator

Apparatus and methods for reducing noise and distortion in current digital-to-analog converters (IDACs). Compensating capacitors may be connected to current sources in an IDAC. The compensating capacitors may be driven with signals 5 derived from the output of the IDAC to cancel transient current sp...

Zusammenfassung:Apparatus and methods for reducing noise and distortion in current digital-to-analog converters (IDACs). Compensating capacitors may be connected to current sources in an IDAC. The compensating capacitors may be driven with signals 5 derived from the output of the IDAC to cancel transient current spikes that would otherwise occur on the output of the IDAC.
