Digital to analog converter having improved noise and linearity performance |
摘要 |
A digital to analog converter converts an N-bit digital signal into an M-bit digital signal and provides the M-bit digital signal to a conversion circuit which converts the M-bit signal to an analog output signal. The analog output signal is sampled and fed back across the discrete time/continuous time interface to the input of the conversion circuit. An interpolation filter is used to increase the apparent sampling rate of the incoming N-bit signal.
