چکیده
A modified inductance-capacitance voltage controlled oscillator (LC-VCO) topology is presented in this paper. NMOS only varactor has been used instead of variable capacitance. The frequency of oscillation of the VCO is 7.68GHz with a power dissipation of 5.68mW. The designed oscillator is characterized by a tuning range of 26.73%. Compared to the reference circuit, there is an improvement in frequency of oscillation of the LC-VCO. The design is verified using SPICE simulations. Key WordsInductance Capacitance-Voltage Controlled Oscillator, Ultra-wideband frequency, VCO.
