A force/sense voltage-mode DAC coupled with multiple transconductance amplifiers that generate a correction current injected to a node in one of the DAC cells is discussed. The correction current injected into the DAC cell may reduce nonlinearity produced by biasing current to the operational amplifiers in the DAC.
