Abstract
The clock signal for the sample and hold circuit for sampling the C-V conversion circuit output generated by the control signal generation circuit is different in period from the clock signal for switched capacitor filter circuit for filtering the sample and hold circuit output such that the clock signal for the switched capacitor filter circuit is unchanged in period between the measuring and self-diagnostic modes.
