Abstract
A voltage-controlled oscillator comprises a tank circuit and first and second pairs of transistors. Each transistor comprises a gate, a drain, and a source. The drains of the first pair are coupled to the tank circuit and the gates of the first pair are cross-coupled with the drains of the first pair. The drains of the second pair are coupled to the tank circuit and the gates of the second pair are cross-coupled with the drains of the second pair. The oscillator includes a first resonant filter comprising a first terminal coupled to the sources of the first pair and a second resonant filter comprising a first terminal coupled to the sources of the second pair. A method includes adjusting capacitance in a resonant filter to cause the resonant filter to resonate based on a selected frequency.
