Abstract: A system operable between a charging mode and a transferring mode for measuring capacitance of a capacitive sensor, includes a switching unit configured to, in a first phase of the charging mode, arrange the capacitive sensor to be charged by a first supply voltage from a first end of the capacitive sensor until a voltage difference between the first end and an opposite second end of the capacitive sensor reaches a first predetermined voltage, and in a second phase of the charging mode, disconnect the first end of the capacitive sensor from the first supply voltage and couple the second end of the capacitive sensor (10) to a second supply voltage to raise a voltage at the first end of the capacitive sensor to a second predetermined voltage.

Abstract: Circuitry for providing an oscillating output signal in connection with an integrated circuit chip. This circuitry includes a crystal, off the chip and oscillator circuitry, on the chip, for electrically coupling with the off-chip crystal and operable to produce the oscillating output signal. The preferred embodiment further includes testing circuitry, on the chip, for evaluating whether the oscillating output signal is operating within an acceptable range, as well as operational recovery circuitry, on the chip, for attempting to restore the oscillating output signal, in response to the testing circuitry evaluating that the oscillating output signal is not operating within an acceptable range.
