Abstract :
A differentially tuned varactorless VCO is implemented in a 0.13μm CMOS process. The frequency is continuously tunable from 23.2 to 29.4GHz (23.6% range differential and 3.3% range for common-mode tuning) using a single-ended (1.5V max) tuning voltage. Measured phase noise at 26.6GHz is -96.2dBc/Hz (3MHz offset) and the open-drain output buffer delivers -11dBm (single-ended) to a 50Ω load. The 0.3 × 0.4mm2 core consumes 43mW (6.5mW in the output buffer) from a 1.2V supply.
