Digital to analog converter |
摘要 |
A segmented DAC is described in which the outputs of a pair of subword DAC circuits are summed by modulating the offset voltage of a differential buffer amplifier. Also described are various alternative DAC embodiments and an operational amplifier input stage in which modulation of the offset voltage of a differential amplifier responsive to a digital signal is accomplished using interpolation techniques for eliminating errors in linearity and monotonicity arising from component inaccuracies.
