In this paper, a novel method to realize LC Voltage-Controlled-Oscillator (LC-VCO) operating at 76.2–76.7[Formula: see text]GHz frequency band for microwave RFIC component is presented. The model of cross-coupled differential LC-VCO is designed in 45[Formula: see text]nm technology using Complementary Metal Oxide Semiconductor (CMOS) process for Frequency Modulated Carrier Wave (FMCW) automotive radar sensors and RF transceivers application. The impact of VDD, control voltage and temperature variation on frequency shift, phase noise, and output power has been analyzed to optimize the trade-off between frequency, phase noise, and power requirement. The results depict that LC-VCO dissipates 10.45[Formula: see text]mW power at an operating voltage of 1.5[Formula: see text]V. The phase noise has been observed to be [Formula: see text]90[Formula: see text]dBc/Hz at 1[Formula: see text]MHz offset at 76[Formula: see text]GHz carrier frequency. The estimated layout area of IC is [Formula: see text]m2. The result shows the edge of the design over existing techniques.
