摘要	In this brief, we proposed a small area, high precision, and high energy efficiency single-ended capacitance-to-digital converter (CDC). The circuit incorporates a $\Delta \Sigma $ CDC and a SAR CDC. The SAR CDC is a coarse CDC which determines the measurement range of capacitance, considering the area consumption, single-ended SAR CDC is adopted. To get a high resolution, inverter-based correlated-double-sampling (CDS) circuit is employed in the $\Delta \Sigma $ modulation loop. The test chip is fabricated in a 180-nm CMOS process and the core occupies an area of 0.15mm2. The circuit achieves an rms resolution of 186aF at a 4pF input capacitor, the power consumption is $4.1~\mu \text{W}$ in SAR phase with a 100kHz sampling rate and $23.2~\mu \text{W}$ in $\Delta \Sigma $ phase with a 400 kHz sampling rate.
