Abstract
Methods and systems for a multi-core multi-mode voltage-controlled-oscillator (VCO) may comprise generating a plurality of oscillating signals utilizing a plurality of voltage controlled oscillators (VCOs) arranged symmetrically on an integrated circuit, where interconnects for the VCOs may be arranged in quiet zones at locations equidistant from each pair of the plurality of VCOs. An interconnection ring may be centered within the arranged VCOs that comprises at least two conductive lines that couple to output terminals of each of said plurality of VCOs. The plurality of VCOs may receive control signals from interconnects coupled to at least one conductive line in the interconnection ring. The plurality of VCOs may receive control signals from a conductive line in said interconnection ring. A positive terminal of a first VCO of a pair of adjacent VCOs of the plurality of VCOs may be coupled to a same conductive line of the interconnection ring as a negative terminal of a second of the pair of adjacent VCOs. The interconnection ring ay be circular. Impedances may couple the VCOs to the interconnection ring. Bias signals may be communicated to each of the plurality of VCOs from the interconnection ring. The plurality of VCOs may include four VCOs arranged equidistant from a center point.
