Abstract
Embodiments provide a multi-phase voltage controlled oscillator (VCO) that produces a plurality of output signals having a common frequency and different phases. In one embodiment, the VCO may include a passive conductive structure having a first ring and a plurality of taps spaced around the first ring. The VCO may further include a capacitive load coupled to the passive conductive structure, one or more feedback structures coupled between a pair of opposing taps of the plurality of taps, and one or more current injection devices coupled between a pair of adjacent taps of the plurality of taps.
