摘要:
A hybrid Nyquist thermometer and sigma delta digital to analog converter is presented. The digital input signal is divided into most significant bits and least significant bits. The most significant bits are converted to a thermometer code. A thermometer element array is controlled by the thermometer code. A fractional value is calculated from the least significant bits and used to dither the first unexercised array element in order to get finer resolution with guaranteed monotonicity.
