Abstract

The invention discloses CMUTSThe frequency tracking circuit of resonant mode biochemical sensor, including biasing networks, impedance matching network, CMUTs network, load capacitance network and BJT amplify feedback network.Biasing networks provide DC voltage for CMUTs and avoid current overload.Impedance matching network, which is tuned, makes CMUTs form series parallel resonance region.Based on BJT and load capacitance network, oscillator signal positive feedback is formed, realizes that CMUTs parallel resonant point oscillator signal exports in real time.The present invention makes CMUTs form series parallel resonance region at low voltage, the resonance circuit is simple and convenient, the starting time is Microsecond grade, can export CMUTs resonance frequency in real time, be of great significance to the portable and real-time detection application based on CMUTs resonant mode biochemical sensor.
