摘要
An oscillator apparatus (100) includes an oscillator core circuit (105). The oscillator core circuit (105) includes an inverting transconductance amplifier (1052), at least one first capacitor (1053A, 4053A), at least one second capacitor (1053B, 4053B), and a resonator (1054). The at least one first capacitor (1053A, 4053A) is connected between an input of the inverting transconductance amplifier (1052) and a ground level. The at least one second capacitor (1053B, 4053B) is connected between an output of the inverting transconductance amplifier (1052) and the ground level. The resonator (1054) has a first port connected to the input of the inverting transconductance amplifier (1052) and a second port connected to the output of the inverting transconductance amplifier (1052). The first port is decoupled from the second port.
