ULTRA WIDE BAND VCO USING CMOS TECHNOLOGY Seema Malik, Mr. Sunil Kumar M.Tech (VLSI Design), Banasthali University, Banasthali, Jaipur, Rajasthan, INDIA 2 Scientist (Agriculture Statistics), Project Directorate for Farming System Research, Modipuram, Meerut (U.P) 250-110, INDIA ___________________________________________________________________________________ Abstract: Ultra wideband (UWB) wireless technology has promoted designing devices covering wide bandwidth over several GHz. UWB oscillators that should achieve very wide tuning range along with low phase noise performance. Wideband (Ultra Wideband) oscillators can be realized by carefully designing passive and active devices. The techniques for sizing and layout design of active and passive elements are discussed to optimize the phase noise performance of oscillators. We will design and simulate CMOS VCO capable of multi-GHz and wide tuning range. The VCO will be based on inductive tuning, realized by the tunable active inductor (TAI) using CMOS technology that can provide a tuning range between 0.5–2.5 GHz using Hartley structures. The project also deals with some phase noise reduction techniques such as PLL-based feedback and harmonic tuning.
