  • CIRCUIT FOR IMPLEMENTING A CONTINUOUS-TIME DEGLITCHING TECHNIQUE FOR DIGITAL ANALOG CONVERTERS
    Publication number: 20140210656
    Abstract: A processor and a circuit implementing a continuous-time deglitching technique for a digital-to-analog converter are disclosed. The circuit includes a digital-to-analog converter having a differential current output, an operational amplifier having an inverting input coupled to a first output of the differential current output and a non-inverting input coupled to a second output of the differential current output, and a transistor coupled to the second output and the output of the operational amplifier. The operational amplifier is configured to operate the transistor to adjust the voltage potential of the second output to substantially match the voltage potential of the first output.
