Abstract :
Design of CMOS high-speed self-regulating voltage-controlled oscillator (HSSR VCO) using negative skewed delay scheme is presented in this paper. With a SMIC standard logic 0.18-μ 1.8V CMOS process, the simulation results show that the HSSR VCO can work at 2.2 GHz with good linearity in frequency-voltage space as over an acceptable tuning range as well as a built-in compensation for the delay variation caused by supply fluctuation.
