“…The FOM is a numerical expression representing the efficiency of a given system. The FOM can be calculated as SSB noise at the offset ∆f from its carrier frequency with the log of the ratio of the different carrier frequencies to its offsets frequencies, which is normalized with the square, and it's multiplied with the VCO core power dissipation [98], [131], [165]- [167]. 4) FTR analysis of the Reported VCOs Fig.…”

Voltage-controlled Oscillator (VCO) is a prominent part that has been used to generate a stable frequency for the high-frequency transceiver system. This survey encompasses a comparative analysis of two commonly used VCO architectures: the Ring VCO and LC-VCO. The Ring VCO has been constructed with the collection of ring delay cells. Moreover, the LC-VCO utilizes inductors, capacitors, fine-tuning circuits, coarse-tuning circuits to generate frequency. Furthermore, this study investigates an in-depth exploration of VCO structures, operational principles, advantages, limitations, and performance metrics. In addition, it evaluates performance parameters, including operating frequency range, phase noise, figure of merit, and tuning techniques. This research suggests that based on the application and its requirements, the VCO performance parameters need to be varied. This survey employs diverse types of VCO, and its design methods. Implications for future research and study of VCO design and integration are discussed.

“…The output power of a fully-fledged VCO from APITech [35] ranges from 7 -10 dBm minimum. These VCOs typically include amplifiers and buffer circuitry, increasing output power [36]. In the designed VCO, neither a buffer nor a Darlington configuration was used to drive the load.…”

A differential cross-coupled Voltage Controlled Oscillator (VCO) has been designed using the Double-Gate (DG) MOSFET for VHF applications. The DG MOSFET exhibits superior noise immunity with its high noise figure and is suitable for low-power, high-frequency applications. The proposed VCO has been designed using a differential topology with improved power consumption, design flexibility, and noise reduction. This also improves the high-frequency performance of existing differential amplifiers. Thereafter, the proposed VCO was compared with fabrication and design methods, particularly Silicon-based CMOS and Single-Gate (SG) MOSFET VCOs, as possible alternatives. Various printed circuit board (PCB) design practices were followed to minimise the noise and improve the overall efficiency of the circuitry. Key parameters for the analysis of this VCO are the output power, phase noise, and figure of merit, which have been realised as -2.91 dBm at peak and -69.79 dBc/Hz at 1 MHz, respectively. The power consumption of the designed VCO is 36 mW.
