Design of a 2.5-GHZ QVCO robust against high frequency substrate noise

This work presents the design procedure followed to obtain a low‐power voltage‐controlled oscillator (VCO) robust against high‐frequency substrate noise, using as a demonstrator a 2.5 GHz VCO with quadrature outputs (QVCO) based on a 5‐GHz LC tank resonant VCO (LC‐VCO) and frequency divider. A simpl...
