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 radio frequency signal must be amplified by the power amplifier and then propagated into the air through the antenna. Therefore, the performance of the power amplifier has a vital impact on the entire transmitter system [3]. In the signal transmitting chip, the power amplifier, as the last stage of the transmitter, is an energy-consuming device, and its power consumption accounts for about 40% of the total power consumption of the entire chip.…”

As the rapid development of 5G system and wireless communication technology, communication systems emphasize more on high-speed and stable information transmission and energy consumption, which directly promotes the update iteration of RF hardware design. As an energy-consuming device and the last stage device of the transmitter, the power amplifier determines the overall performance of the transmitter system. Theoretically, the class E power amplifier can reach 100% efficiency, the energy utilization rate is high, and it has the advantages of simple structure. Therefore, in the environment of highly integrated design and rapid development of mobile devices, Class E power amplifiers with high efficiency have gradually attracted people's attention.
