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 adjustment of the natural frequency of a micro crystal resonator (MCR) is the key requirement in its manufacturing, which determines the actual performance of the product. Laser processing is a new method for MCR frequency modulation, and its process parameters directly affect the frequency modulation effect. Aiming at the laser processing equipment for MCR frequency modulation, the structure of the laser processing control system for MCR frequency modulation is designed by analyzing the requirements of a laser processing control system. The working flow of the laser processing control system for MCR frequency modulation is studied, the motion control method of the laser processing platform for MCR frequency modulation is proposed, and the laser processing control system for MCR frequency modulation is designed. By analyzing the laser characteristics for MCR frequency modulation, an orthogonal experiment is carried out to optimize the laser processing parameters for MCR frequency modulation.

“…Active filters and controlled oscillators are fundamental components because their high performance [4,5]; however, these devices present a trade-off between the power consumption and performance as a result of the dielectric and conductive losses associated to the high operation frequency and their own power dissipation [6][7][8][9][10]. A current option to replace them maintaining an acceptable performance, is to use tunable piezoelectric devices.…”

The linear behavior of piezoelectric materials is well known from a century ago, but also, the non-linear behavior for these material have found a novel way of applications. Currently, the new technologies as the fifth generation of telecommunications (5G) and Internet of Things (IoT) are demanding high requirements for the performance of the devices operating under these technologies e.g. high quality factor, high thermal efficiency and device fabrication compatibility with the standard fabrication processes for integrated circuits as CMOS, FD-SOI and FinFET. In this work, the non-linear state equations for piezoelectric effect in stress- charge formulation, the transformations laws and the high order tensors structures are presented, in order to allow an easy way to implement it on FEM simulation software. The non-linear behavior of piezoelectric materials is discussed, and taking into account the analysis done in this work, three ways to implement nonlinear effects to design tunable piezoelectric devices for 5G and IoT applications are presented.
