DIFFERENTIAL CRYSTAL OSCILLATOR CIRCUIT |
摘要 |
A differential crystal oscillator circuit, including: first and second output terminals; 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 a resistor connected between gate and drain terminals, wherein the first MOSFET diode couples to the first transistor to provide low-impedance load at low frequencies and high-impedance load at higher frequencies to the first transistor, wherein the second MOSFET diode couples to the second transistor to provide low-impedance load at low frequencies and high-impedance load at higher frequencies to the second transistor; and a reference resonator coupled between the first and second output terminals to establish an oscillation frequency. |
