Digital to analog converter and a ground offset compensation circuit
Abstract:
A digital to analog converter comprising: a digital to analog conversion core adapted to receive at least one reference voltage and a digital word to be converted, and to output an analog voltage as a function of the digital word and the at least one reference voltage; a sensing circuit for sensing a difference between a first ground voltage associated with an output of the digital to analog converter and a ground reference voltage occurring at the digital to analog converter; and a compensation circuit for applying a compensation voltage to the at least one reference voltage used by the conversion core of the digital to analog converter.
