A Temperature Compensation Voltage Controlled Oscillator Using a Complementary to Absolute Temperature Voltage Reference
This paper presents a temperature compensation voltage controlled oscillator (VCO) based on Cross-Coupled pair and Colpitts structures which is suitable for military fields. Also, two inductors have been used for increasing the negative conductance. By using this method, start-up condition has been improved. Two varactors and a simple capacitor bank are applied for covering a wide tunning range...
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 اولVoltage-controlled Oscillator-based A/D Conversion
There has recently been increasing interest in developing highly digital analog-to-digital converter (ADC) structures for on-chip testing and ease of integration in future CMOS processes. An intriguing circuit to utilize in such cases is a ring oscillator voltage-controlled oscillator (VCO), which outputs a clock waveform whose frequency is a function of an input tuning voltage. By comparing th...
متن کاملA Low- Voltage Current-Controlled Oscillator
A new current-controlled oscillator (CCO) is presented which is suitable for use in low-voltage and lowpower designs. These features, and the low supply dependence of this CCO all stem from using a regenerative mechanism in its primitive delay cells. The circuit is designed and simulated in a 0.8um BiCMOS technology.
متن کاملA 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...
