Abstract
An oscillator circuit with an oscillator stage and a first current source arranged to drive the oscillator stage is presented. The oscillator stage has an oscillator stage input terminal, an oscillator stage output terminal, an oscillator arranged to provide an oscillating signal between the oscillator stage input terminal and the oscillator stage output terminal. The oscillator circuit has an operational amplifier with an inverting input, a non-inverting input and an operational amplifier output. The oscillator stage input terminal and the oscillator stage output terminal are coupled to the inverting input and non-inverting input. The operational amplifier output is coupled to the oscillator stage input terminal such that the oscillator stage input terminal and the oscillator stage output terminal are controlled to have a same DC voltage level.
