Abstract This thesis deals with the design and comparative analysis of di erent architectures of on-chip LC voltage controlled oscillators. One of the earliest multiphase clock generation techniques for creating quadrature phases (0°, 90°, 180°, and 270°) was the quadrature VCO (QVCO). In this work LC-Cross coupled VCO was employed to achieve compact design. INTRODUCTION The demand for a higher data rate and further miniaturization in wireless applications like communications, sensor networks and geo-positioning drives the development of large scale system-on-chip in CMOS technology. G. 6 GHz LC-tank VCO with an integrated LDO is designed using a 65 nm CMOS process. 5D electromagnetic simulator (SONNET) to design the optimum inductor, while the varactor is designed using S-parameter simulation in Sam Palermo Analog & Mixed-Signal Center Texas A&M University Abstract—This paper presents the design and performance analysis of a CMOS Voltage-Controlled Oscillator (VCO) implemented using Cadence Virtuoso with the GPDK 90nm technology node. This is now combined with the knowledge about CMOS devices from the previous chapter to select a set to design optimal tanks. The optimization of the tank-Q automatically leads to We use these considerations to design a multi-harmonic class-B LC-VCO in 22nm FDSOI CMOS, which offers two outputs - one at the fundamental (H1) and another at the fourth harmonic (H4), extracted directly from the core. 2025. 157-160, produced at AMD-ITC-1350-0185110-14. To prove the concept, a four-core coupled oscillator is fabricated in a 130nm CMOS RF SOI process. 4 dBc/Hz compared to the conventional sequential design method. The aim of To achieve low-power consumption and low-phase noise performance in an LC VCO, it is essential to design and optimize the tank with minimal combined inductance and capacitance loss (R), leading to maximum L/R and L/C ratios [1]. I. The component values are shown in tables 1-2. The Keywords-component - LC-tank, VCO, phase noise, thermal noise, flicker noise, phase locked loop. 8%, with FoM increased by 2.
