| description |
A 7-GHz CMOS voltage controlled ring oscillator that
employs multiloop technique for frequency boosting is presented in
this paper. The circuit permits lower tuning gain through the use of
coarse/fine frequency control. The lower tuning gain also translates
into a lower sensitivity to the voltage at the control lines. Fabricated
in a standard 0.13µ m CMOS process, the proposed voltage-controlled
ring oscillator exhibits a low phase noise of 103.4 dBc/Hz
at 1 MHz offset from the center frequency of 7.64 GHz, while consuming
a current of 40 mA excluding the buffer. |
