Claim 12:
13. The device of claim 1, wherein the DSC further comprises:
a comparator configured to produce the error signal based on comparison of the reference signal to the drive signal, wherein the reference signal is received at a first input of the comparator, and the drive signal is received at a second input of the comparator;
a dependent current supply configured to generate the drive signal based on the error signal and to provide the drive signal via the single line that couples to the resonating capacitor and the second input of the comparator; and
an analog to digital converter (ADC) configured to process the error signal to generate the digital signal representative of the one or more electrical characteristics of the drive signal.
