摘要：A differential crystal oscillator circuit, including: first and second outputterminals; a cross-coupled oscillation unit including first and second transistors cross-
coupled to the first and second output terminals; first and second metal-oxide
semiconductor field-effect transistor (MOSFET) diodes, each MOSFET diode including aresistor connected between gate and drain terminals, wherein the first MOSFET diodecouples to the first transistor to provide low-impedance load at low frequencies andhigh-impedance load at higher frequencies to the first transistor, wherein the secondMOSFET diode couples to the second transistor to provide low-impedance load at lowfrequencies and high-impedance load at higher frequencies to the second transistor; anda reference resonator coupled between the first and second output terminals toestablish an oscillation frequency.
