A 6.8GHz CMOS monolithic oscillator with a 5.9dBm output power has been dem
onstrated by 0.35 mum 1P4M CMOS technologies. The oscillator was designed b
ased on a home-made modified BSIM3v3 large-signal model, where the high-fre
quency parasitics were included. In addition, on chip spiral inductors and
MIM capacitors for the resonant circuit were characterised and used in this
monolithic oscillator circuit.
