Claim Text:
1. An apparatus comprising: a plurality of LC-based voltage-controlled oscillators (LC VCOs) connected in parallel to a common control input, each LC VCO having an output for outputting an oscillating signal based on the common control input, and a frequency/phase adjustment input; an averaging circuit connected to the output of each LC VCO to generate a common output comprising an average of the outputs of the plurality of LC VCOs; a frequency comparator connected to the output of each LC VCO to determine a frequency mismatch between one or more of the LC VCOs, and connected to the frequency/phase adjustment inputs of the LC VCO to electronically adjust a capacitance or an inductance of one or more of the LC VCOs to reduce the frequency mismatch.
