Abstract	The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is based on biquad sections, and the ∆Σ ADC system is based on a lowdistortion modulator topology. The feasibility of the proposed idea is demonstrated with system and circuit level.
