Abstract

The invention discloses a silicon micro resonant frequency multiplier based on a superharmonic synchronization technology. A resonance module is a long-distance-shaped resonance beam, and two clampedmodules form two-end fixed support; the lower end of the resonance beam is arranged on a monocrystalline silicon substrate in a suspended manner, an excitation module is arranged in the middle of oneside of the resonance beam, and a detection module is correspondingly arranged in the middle of the other side, wherein the excitation module and the detection module are both fixed on the monocrystalline silicon substrate; the excitation module is connected with the signal input module, and the detection module is connected with the oscillation module; two ends of the resonance beam are each connected with a piezoresistive frequency modulation module to generate a potential difference resonance beam body, the oscillation frequency of the oscillator is adjusted through the joule heat effect, and the superharmonic synchronization phenomenon of different orders is realized. Frequency multiplication amplification of the ultra-high order number can be achieved, and the limit of the frequency multiplication frequency of an existing frequency multiplier is broken through.

Description

technical field [0001] The invention belongs to the technical field of micromechanical systems and frequency processing, in particular to a silicon micro-resonance frequency multiplier based on super-harmonic synchronization technology. Background technique [0002] With the continuous development of computer systems, communication systems, navigation, aerospace, digital TV, and satellite positioning, the requirements for low spurious, low noise, spectral purity, frequency range, and frequency stability of frequency sources are getting higher and higher. Frequency multipliers are mostly used in microwave and millimeter wave transmitter and receiver circuits to generate high frequency signal sources that cannot be obtained on fundamental frequency oscillators. For example, in a handheld mobile phone, a frequency multiplier can be used as an important component to increase the frequency of the carrier signal. After the signal is processed by frequency doubling, the frequency ...
