Abstract
An integrated circuit DAC device and fabrication method are provided with a linear bias ladder circuit which generates a plurality of bias voltages, an inverting operational amplifier configured to generate an analog output voltage in response to an input current signal, and a plurality of MMT devices connected between the linear bias ladder circuit and the inverting operational amplifier to implement a DAC with a first current control gate of each MMT device connected to one of the plurality of N different bias voltages, with a second switch control gate of each MMT device connected to receive one of a plurality digital input code values, with a drain terminal of each MMT device connected to a digital bias voltage (Vdbias), and with a source terminal of each MMT device connected to provide the input current signal to the inverting operational amplifier.
