Abstract:
A digital-to-analog converter includes a voltage-to-current converter, a current-mode digital-to-analog converter and an operational amplifier. The voltage-to-current converter generates a first current signal, and the current-mode digital-to-analog converter generates a second current signal. The operational amplifier modulates a drain current in response to the second current signal and generates an output signal having an offset.
