H Igh P Erformance V Oltage C Ontrolled O Scillator ( Vco ) Using 65 Nm Vlsi T Echnology

CMOS" refers to both a particular style of digital circuitry design, and the family of processes used to implement that circuitry on integrated circuits (chips). CMOS circuitry in VLSI dissipates less power when static, and is denser than other implementations having the same functionality. As this advantage has grown and become more important, CMOS processes and variants for VLSI have come to dominate, so that the vast majority of modern integrated circuit manufacturing is on VLSI technology processes. A key circuit use in modern communication is voltage control oscillator VCO’s output is a AC waveform whose frequency is dependent upon the input voltages. In today’s wireless communication system, greater maximum frequency required by the VCO w.r.t. to the digital phones that use these circuit, low power consumption, small size & low fabrication cost are important design factor. The layout of VCO which is develop by us is a modified design of high performance VCO .This is a optimum design for use in industries at 65 nm VLSI technology . In the estimated design ,more emphases is given on power consumption, layout design and many more. This report is a brief study of high performance VCO on 65 nm VLSI technology to achieve some objectives as mention above
