title = "A Low-Power-Consumption Capacitance to Digital Converter with Novel Calibration Technology",
abstract = "Currently, capacitive sensors are extensively applied in environmental monitoring, medical equipment, automotive electronics, and so on. However, conventional capacitive sensor readout circuits based on analog to digital converter (ADC) architecture have a high power consumption and lack the self-calibration function. This paper presents a low power consumption capacitance to digital converter (CDC) circuit with calibration. The circuit can achieve a high-precision monitoring for capacitive sensors with low-frequency variation. The detectable capacitance range is 0pF to 5pF. The simulated maximum absolute error of CDC is 26.3fF. The application specific integrated circuit (ASIC) is fabricated in 180nm CMOS process. The chip area is 1.4mm×1.05mm. Experimental results demonstrate that the measured absolute error is less than 0.1pF.",
