Abstract
An oscillating device includes a first quartz crystal resonator, a driving circuit, a first waveform adjustment circuit, and at least two second quartz crystal resonators. The first quartz crystal resonator has a first resonant frequency. The driving circuit, coupled to the first quartz crystal resonator, drives the first quartz crystal resonator to generate a first oscillating signal having the first resonant frequency. The second quartz crystal resonators, coupled in parallel and coupled to the driving circuit and the first quartz crystal resonator, have a second resonant frequency and receive and rectify the first oscillating signal to generate a second oscillating signal having the second resonant frequency. The first waveform adjustment circuit, coupled to the second quartz crystal resonators, receives the second oscillating signal and adjusts the second oscillating signal to generate a first waveform adjustment signal.
