“…In the last two decades, VCO design engineers are working to improve all the critical constraints including frequency band, phase-noise, power dissipation, the figure of merit, and occupied layout area while building VCOs. Hence, various differential VCO modeling strategies have already been developed to magnify these critical parameters [8][9][10][11][12][13][14][15][16][17][18]. A VCO with a fully switching differential dual delay stage is reported in [8] to enhance the performance of phasenoise, but it suffers from a low-frequency range.…”

“…The improvement in phase-noise is achieved by decreasing the thermal noise of channel throughout the output signal's voltage transition for the low supply voltage [13]. The design of VCOs with tunable active inductors is reported in [14][15] to obtain a higher frequency range at the cost of degraded phase-noise performance. Active inductor based, fully differential VCO is proposed in [16][17] to achieve good phase-noise performance by offering a penalty in large power dissipation.…”

This paper reports a design of the most significant electronic circuit used in modern wireless and optical communications systems, known as voltage-controlled oscillator (VCO). A variable delay stage is a core element of ring VCO and in this work, a new differential delay stage based on the inductive shunt peaking technique using active inductors (AI) is presented to increase the ring VCO’s frequency bandwidth. The presented four-stage ring VCO architecture with a new differential delay stage utilizes the dual delay path scheme to achieve high oscillation frequency, low power dissipation, and low phase noise. The proposed VCO circuit is designed and simulated in a 180 nm TSMC CMOS process and 1.8 V supply voltage (Vdd). The VCO generates an output frequency range from 2.876 GHz to 2.039 GHz (34.05%) for 0 V to 1 V variation in control voltage (Vc). The designed VCO circuit's power dissipation ranges from 3.289 mW to 2.888 mW, and its phase-noise at 1 MHz offset frequency is -108.9 dBc/Hz. The VCO exhibits figure of merit is -171.9 dBc/Hz and a layout area of 1148.67 µm2.

“…VCO may be realized with many configurations according to the applications and performance requirements. The available fundamental approaches are ring oscillator [1]- [3], inductance-capacitance (LC) oscillator [4], [5] tunable active inductor (TAI) based oscillator [6], [7], and relaxation oscillator [8]. Apart from the phase noise (PN); tuning range, power consumption, and output waveform are also necessary VCO specifications.…”

Voltage controlled oscillator (VCO) offers the radio frequency (RF) system designer a freedom to select the required frequency. Today's wireless communication system imposes a very stringent requirement in terms of phase noise generated in VCO. This study presents an inductive source degeneration technique to improve the phase noise performance of the inductance-capacitance (LC)-VCO. Double cross-coupled topology has been chosen for the proposed VCO. The post layout simulations with the parasitic resistance, inductance, capacitance (RLC) extracted view is carried out with united microelectronics corporations (UMC) 0.18 µm process by spectre simulator of cadence tools. The proposed VCO provides a phase noise of -124.3 dBc/Hz @ 1 MHz. The tuning range obtained is 19.87% with a centre frequency of 2.46 GHz which makes it suitable for industrial, scientific, and medical (ISM) band applications. It consumes a power of 2.10 mW. Also, a good figure of merit of -189 is achieved. The total layout area occupied is 477×545 µm 2 .
