摘要：
To achieve high-resolution in electrically noisy environments as well as low-power, we propose a differential capacitance-to-digital converter (CDC) that utilizes three-level time-domain manipulation of intermediate signals. The proposed CDC, designed in 0.35 mu m digital CMOS technology and simulated with HSPICE, achieves a 9-bit resolution at the power supply of 3.3V with the superimposition of 600mVpp 2.5 kHz square-wave noise disturbance, consuming the average power of 158.3 mu W/sample.
