  Using 0.18 µm technology, CMOS transistors are designed as a VCO prototype. In the proposed VCO structure, an adjustable active inductor and a vector for the LC tank are used. The wide frequency regulation in this circuit is controlled by an adjustable active inductor and fine-tuning with a reactor.VCO with MOS vector in storage mode has the lowest power consumption and the lowest phase noise at large offset frequencies. The benefits of using MOS vectors increase significantly when more advanced CMOS technologies are selected. Due to the absence of passive elements, the fully integrated VCO takes up less chip surface area in the circuit.

  A CMOS voltage controlled oscillator with a wide adjustment range is designed to operate at radio frequencies. The main advantage of this structure is the use of an active inductor. Hence the chip surface is significantly reduced. The active inductor and varactor capacitor in the proposed VCO circuit is used for frequency settings. The results of the measurements using the 0.18 µm CMOS process show phase noise -79.85dBc and amplitude noise -126.9dBm in the 1MHz offset. Also, using the S parameter, the central frequency value for this 3GHz circuit is obtained. Manuscript profile
