Oscillator circuits are used to make accurate and reliable clock signals for systems as simple as a wristwatch and as complicated as satellites, which are important for long-distance communication. There are many ways to build an oscillator circuit, using either passive or active parts. Each option has pros and cons, but at the current level of mobile communication development, the most important things are interoperability and low power use. This need has driven the development of compact, battery-operated electronics, and Very Large-Scale Integration (VLSI)-based ring oscillators provide the ideal solution. These oscillators ought to dissipate less power, have a large tuning range, and be compact. The paper presents a novel Complementary Metal Oxide Silicon (CMOS) ring oscillator that serves as a Voltage Controlled Oscillator. The suggested architecture utilizes the advantages of both a current-starved ring oscillator and a negative-skewed delay by combining their constituent parts. The proposed architecture has a control voltage of 1.15 V and a supply voltage of 2 V, generating a 9.35 GHz dominant frequency with a 13.82% harmonic distortion between the inputs and outputs. The proposed architecture can implement 5G-based applications that require high frequency and low power by carefully selecting the passive components within the design.

“…The application of wireless communication technology has promoted the development of PLLs with low jitter, small area, and low power [1,2,3,4,5]. Voltage-controlled oscillators (VCOs) are the key module of PLLs, which must possess the characteristics of low power and low phase noise to meet the needs of the low power 802.11ah standard for Internet of Things [6,7,8,9,10,11], i.e. in the frequency range below 1 GHz, power consumption and phase noise need to be less than 5 mW and -100 dBc/Hz, respectively.…”

A low phase noise low power ring voltage-controlled oscillator (Ring-VCO) is proposed for phase-locked loops (PLLs) in the 802.11ah communication protocol band. A three-stage Ring-VCO with dual-path structure delay cells is designed to meet the high performance requirements of Internet of Things. The main noise source in the differential delay cell can be eliminated at the differential output, thus reducing phase noise. Implemented in an old TSMC 0.18 µm CMOS process, the Ring-VCO achieves a tuning range of 343.56-974.56 MHz. The phase noise at 1 MHz offset varies from -116.28 to -108.74 dBc/Hz, and the current consumed is 2.27 mA.
