dc.description.abstract | This article describes a fourth-order continuous-time (CT) bandpass (BP)-Delta Sigma capacitance-to-digital converter (CDC) for full-CMOS sensors having ultrahigh-resolution and high-energy efficiency. To improve the resolution of Delta Sigma CDC, a CT instead of a discrete-time (DT) operation is employed to overcome a thermal noise limitation. Moreover, a BP-Delta Sigma modulator is used to save power consumption compared to lowpass (LP) or highpass (HP)-Delta Sigma Ms. In addition, a charge-domain digital-to-analog converter (DAC) at the input stage of the Delta Sigma M is proposed for low thermal noise and simplicity. An inverter-based amplifier is used for low power consumption and gain boosting circuit is added to increase de gain of the amplifier. Implemented in 0.18 mu m CMOS, the proposed CDC achieves a ultrahigh-resolution of 3.68 aF(rms) and the highest Schreier figure-of-merit (FoMS) of 183 dB which is 3.3 dB improvement over the recent state-of-the-art CDCs. | - |
