OSCILLATOR SCHEME CAPABLE OF REDUCING FAR-OUT PHASE NOISE AND CLOSED-IN PHASE NOISE

摘要

Oscillator device (100) includes oscillator core circuit (105). Oscillator core circuit (105) includes inverting transconductance amplifier (1052), at least one first capacitor device (1053A, 4053A), at least one second capacitor C (1053B, 4053B) resonator (1054). Input inversion trsanscondutance amplifier (1052) and ground level are connected between at least one first capacitor device (1053A, 4053A). Connection output inverting transconductance amplifier (1052) and ground level between at least one second capacitor C (1053B, 4053B). Resonator (1054) is connected to input inversion trsanscondutance amplifier (1052) with first port and second port is connected to output (1052). Inverting transconductance amplifier first port and second port decouple.
