Abstract:
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.

Claim (Index 5):
The SAR quantizer of  claim 4 , wherein the lowly-significant-bit switch circuit includes:\n a second capacitor circuit configured to carry out another sampling operation and another charge-redistribution operation according to the analog input signal and a plurality of second reference voltages and thereby generate the L lowly-significant-bit sampling result(s); and a second switch circuit configured to control connection between the second capacitor circuit and each of second reference voltage terminals according to the second control signal, in which the second reference voltage terminals are configured to provide the second reference voltages.
