Abstract
According to one embodiment, a dual voltage controlled oscillator (VCO) circuit includes a first VCO and a second VCO. The first VCO includes: a first variable capacitor having an input node, a first output node, and a second output node, a second variable capacitor coupled in parallel with the first variable capacitor, a first transistor, and a second transistor, where the first transistor has a first drain coupled to the first output node, a first gate coupled to the second output node, and a first source coupled to a ground, where the second transistor has a second drain coupled to the second output node and a second gate coupled to the first output node, and a second source coupled to the ground. The dual VCO circuit includes a second VCO mirroring the first VCO, a first and a second inductors coupled to the first and the second VCO respectively.
