ABSTRACT:
An oscillator is disclosed comprising a pair of gm stages wherein the output of the second gm stage is coupled to the inverting input of the first stage and the output of the latter is coupled to the non-inverting input of the former; first and second capacitors coupled respectively between the outputs of the two gm stages and ground and feedback circuitry coupled between the output of the first gm stage and the non-inverting input of thereof while the inverting input of the second gm stage being coupled to ground. Because the first gm stage is operated as a negative gm, this stage simulates an inductor using the first capacitor that is coupled to the output of the stage.
