A switching circuit includes first and second MOS transistors of the same conductive type. A first set of the plurality of clock signals are used to operate a first latch circuit to allow first data to be conducted to a storage element for a period of time after a rising edge of a first clock signal. A ceramic filter forming the RF filter is fabricated on another substrate. If the verification indicates that the updated balance is different from the verified initial balance, the system can perform a corrective action.
