This paper presents an asynchronous sub-two-step circuit architecture to reduce the complexity and power consumption of internal analog-to-digital converter (quantizer) for Continuous-Time Sigma-Delta Modulator (CTSDM). By using the proposed new circuit topology, only 1/3 of comparators for a 5-...
