  • Electronic device and method for evaluating a variable capacitance
    Patent number: 8219331
    Abstract: An apparatus is provided. The apparatus comprises a digital signal generator, an analog filter, an amplitude modulator, and an analog-to-digital converter (ADC). The digital signal generator has a demodulator and provides a digital excitation signal. The analog filter is coupled to the digital signal generator. The amplitude modulator has a variable capacitor and is coupled to the analog filter. The amplitude modulator also generates an amplitude modulated signal with an amplitude that is a function of the capacitance of the variable capacitor. The ADC is coupled to the amplitude modulator and the demodulator, and the digital signal generator and the demodulator operate synchronously.
