## Abstract A 57‐GHz CMOS voltage‐controlled oscillator (VCO) using tunable LC source‐degeneration for operation frequency and tuning‐range enhancement is demonstrated. The tunable LC source‐degeneration is made by adding two tunable LC tanks, where varactors are used as the needed capacitors, to t
