Abstract
A voltage-controlled oscillator (VCO) includes a cross-coupled differential pair of n-type metal-oxide semiconductor (NMOS) transistors. The VCO further includes an inductor-capacitor (LC) tank circuit coupled to the cross-coupled differential pair of NMOS transistors. The VCO further includes cross-coupled pairs of complementary MOS (CMOS) transistors selectively coupled to the LC tank circuit.
