Claim 18:
19. A voltage controlled oscillator, comprising:
a series resonant resistor-capacitor-inductor circuit having a resonance frequency;
a cross-coupled differential pair of transistors including a first transistor with a first source terminal connected to a first node of the series resonant circuit and a second transistor with a second source terminal connected to a second node of the series resonant circuit;
a first inductor coupled between the first node and a ground node;
a second inductor coupled between the second node and the ground node;
a first capacitor coupled between a control terminal of the first transistor and a drain terminal of the second transistor; and
a second capacitor coupled between a control terminal of the second transistor and a drain terminal of the first transistor.
