A sigma-delta capacitance-to-digital converter (CDC) with a resolution down to 19.3 aF at a bandwidth of 10 kHz, corresponding to a noise level of 0.2 aF/√Hz, is presented. An integrated dielectric loss measurement circuit by means of two parallel channels with different integration times offers a complex permittivity measurement in a single-chip(More)
