Abstract

A voltage-controlled oscillator includes two first inductors having a common node, two varactors respectively coupled to the first inductors, a cross-connected pair coupled to the first inductors, and a reversely tunable source degeneration module coupled to the cross-connected pair. The reversely tunable source degeneration module cooperates with the cross-connected pair to form a negative equivalent capacitance seen into the cross-connected pair from the common node of cross-connected pair and each first inductor. An oscillatory signal pair is provided at the first terminals of the first and second transistors.
