A lOGHz CMOS Distributed Voltage Controlled Oscillator'
VDD A 10 GHz CMOS distributed voltage controlled oscillator (DVCO) is designed in a 0.35pm BiCMOS process technology using only CMOS transistors. The oscillator achieves a tuning range of 12% (9.3 GHz to 10.5 GHz) and a phase noise of -1 14 dBc/Hz at 1 MHz offset from a carrier frequency of 10.2 GHz. The VCO uses two different simultaneous tuning techniques which allow for a coarse and fine I t...
متن کاملطراحی و بهبود مشخصه های ساختاری voltage controlled ring oscillator در تکنولوژی cmos
از خصوصیات بارز vco حلقوی می توان به محدوده تنظیم گسترده، طراحی ساده، سطح سیلیکونی کوچک، مجتمع سازی آسان و تلفات توان پایین اشاره کرد. با این حال،نسبت به اسیلاتورهای lc به دلیل ضریب کیفیت پایین، عملکرد نویز فاز اسیلاتورهای حلقوی به طور کلی بسیار ضعیف است، که این یکی از چالش های مهم در طراحی vco حلقوی می باشد. در فصول ابتدایی این پایان نامه سعی بر بررسی ساختارهای مهم و کاربردی vcoهای حلقوی در کن...
15 صفحه اولCMOS Voltage-Controlled Oscillator Resilient Design for Wireless Communication Applications
Semiconductor process variation and reliability aging effect on CMOS VCO performance has been studied. A technique to mitigate the effect of process variations on the performances of nano-scale CMOS LC-VCO is presented. The LC-VCO compensation uses a process invariant current source. VCO parameters such as phase noise and core power before and after compensation over a wide range of variability...
متن کاملSwitched-capacitor Circuit Techniques in Submicron Low-voltage Cmos
The continued down scaling of submicron CMOS technology forces innovation of practical and economical circuits that will tolerate reduced headroom (reduced power supply voltage) due to lowering of the technology’s maximum allowable voltage. Given the relatively large threshold voltages with respect to the shrinking headroom, a group of widely used analog signal processing building blocks that a...
