Abstract:
1. An oscillator circuit comprising: a first end and a second end of an inductor coupled to a first regenerative circuit; the first end and the second end of the inductor coupled to a second regenerative circuit; a first MOS transistor connected to a second MOS transistor at their drains and sources, respectively, wherein their drains and sources are coupled to a first node; a first capacitor coupled between a gate of the first MOS transistor and the first end of the inductor; a first resistor coupled between the gate of the first MOS transistor and a second node; a second capacitor coupled between a gate of the second MOS transistor and the second end of the inductor; a second resistor coupled between the gate of the second MOS transistor and the second node; a first voltage-controlled oscillator (VCO) output coupled to the first end of the inductor and configured to drive a first function; a second VCO output coupled to the second end of the inductor and configured to drive a second function that is separate and independent of the first function; and a capacitive load equalizing circuit coupled to at least one of the first and second VCO outputs and configured to equalize capacitive loads on the first and second VCO outputs.
