A 1.4-GHz LC-VCO in 0.35um Digital CMOS Technology

摘要

A 1.4GHz LC-tank Voltage Controlled Oscillator (VCO) is implemented with TSMC 0.35um 1P4M digital CMOS technology. The VCO has a tuning range of 150MHz and a power consumption of 20mW. Spiral inductor and varactors are also on-chip and no off-chip components are needed.
