An oscillator is provided that is arranged to function as a simplified receiver. The oscillator has a resonator portion and a non-linear portion, which cooperate to generate an oscillating signal. The resonator portion is positioned to receive a modulated signal. In one configuration, the oscillator operates at a frequency offset from the frequency of the carrier for the modulated signal. In this simple arrangement, the oscillator functions as an active mixer, and generates a product output signal. The output signal is extracted from a high impedance point of the oscillator's non-linear device. The output signal is a demodulated or mixed signal, and may be further processed to detect a data signal. |
