Title
A 7.9-GHz transformer-feedback quadrature VCO with a noise-shifting coupling network
Abstract
This paper presents a noise-shifting coupling network to minimize the phase noise contribution from the coupling devices of quadrature voltage-controlled oscillators (QVCOs). Through capacitive feedback, the noisy currents of the coupling devices are shifted to be orthogonal to their impulse sensitivity function (ISF). Fabricated in 65nm CMOS technology, a 7.9-GHz QVCO prototype measures phase noise of -143dBc/Hz at 10-MHz frequency offset and a minimum IQ phase error of 0.23 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sup> . The QVCO consumes 27.2mW with a 0.8-V supply voltage, corresponding to figure-of-merit (FOM) of 186.6 dB.
