Abstract
Certain aspects of the present disclosure are directed towards a voltage-controlled oscillator (VCO). The VCO may include: a first n-type metal-oxide-semiconductor (NMOS) transistor having a gate coupled to a first output of the VCO; a second NMOS transistor having a gate coupled to a second output of the VCO; a first NMOS cascode transistor coupled in cascode between the first NMOS transistor and the second output; and a second NMOS cascode transistor coupled in cascode between the second NMOS transistor and the first output, wherein gates of the first NMOS cascode transistor and the second NMOS cascode transistor are coupled to a common-mode voltage (Vcm) node of the VCO.
