Abstract: Embodiments of the present invention may provide a method of measuring an unknown capacitance of a device. The method may comprise the steps of driving a test signal to a circuit system that includes a current divider formed by the device with unknown capacitance and a reference capacitor; mirroring a current developed in the reference capacitor to a second circuit system that includes a measurement impedance; measuring a voltage within the second circuit system; and deriving a capacitance of the unknown capacitance based on the measured voltage with reference to a capacitance of the reference capacitor and the measurement impedance.

Abstract: The present disclosure provides a pulse generator which generates a pulse train by mixing pulses of a first clock having a first frequency, with pulses of a second clock having a second frequency. Over a predefined time period, the combination of pulses results in a pulse train having an effective frequency which is between the first and second frequencies. A multiplexer is used to select which of the first and second clocks should be provided to the output. Depending on the desired target frequency, the multiplexer is controlled to mix differing amounts of pulses from the first and second clocks. A multiplexer is controlled by a control signal, which is generated using combinatorial logic using the first clock as an input. The pulse generator may be used, for example, as a clock for a charge pump.
