Abstract :
This paper proposed a novel interactive current-reused QVCO (ICR-QVCO) architecture based on capacitor-coupling self-switching sinusoidal current biasing (CSSCB) phase noise reduction technique. These interactive generated quadrature outputs have minimum phase error arising from the mismatch due to process variation and construct the better quadrature phase relationship than ones with conventional QVCO structures. The measured phase noise at an offset of 1 MHz from 4.84 GHz is -125.84 dBc/Hz, which correspond to FOM of -194 dBc/Hz.
