Successive approximation register quantizer and continuous-time sigma-delta modulator
Disclosed is a successive approximation register (SAR) quantizer and a continuous-time sigma-delta modulator (CTSDM) using the SAR quantizer. The SAR quantizer is capable of generating M highly-significant bits as a digital output signal, and generating L lowly-significant bit(s) for the execution of noise shaping operation. Therefore, the SAR quantizer and the CTSDM can reduce the demand for the circuit area of a digital-to-analog converter and lower the delay of a critical path, so as to improve the performance and cut the cost.
