Abstract
A very low-phase-noise quadrature voltage-controlled oscillator is presented, featuring an inherently better figure of merit than existing architectures. Through an improved circuit schematic and a special layout technique, the phase noise of the circuit can be lowered. The circuit draws 15 mA from a 2-V supply. The phase noise is -133.5 dBc/Hz at 600 kHz and the tuning range is 24% wide at a center frequency of 1.57 GHz
