Abstract: An oscillator apparatus includes an oscillator core circuit. The oscillator core circuit includes an inverting transconductance amplifier, at least one first capacitor, at least one second capacitor, and a resonator. The at least one first capacitor is connected between an input of the inverting transconductance amplifier and a ground level. The at least one second capacitor is connected between an output of the inverting transconductance amplifier and the ground level. The resonator has a first port connected to the input of the inverting transconductance amplifier and a second port connected to the output of the inverting transconductance amplifier. The first port is decoupled from the second port.
