ABSTRACT:
A integrated circuit digital to analog converter converts an M-bit digital signal to an analog output signal. The analog output signal can be used to drive external devices such as an off-chip driver. The output of the external device is sampled and fed back across the discrete time/continuous time interface on the chip to the input of the analog to digital converter. Taking the feedback point after the external device ensures relatively high performance for noise and linearity using relatively low performance components, both on and off the chip.
