摘要：
This paper reports a voltage-controlled oscillator (VCO)-based single-loop continuous-time (CT) Sigma Delta analog-to-digital converter (ADC) that does not need any OTA-based analog integrator. It achieves the second-order noise shaping by cascading two VCO-based integrators and removing the sampling operation in the first VCO-based integrator. Behavioral simulations confirm the validity of the proposed ADC architecture.
