Design and Analysis of Voltage Controlled Oscillators in 45nm CMOS Process

Also Available Domains Transistor Logic|Cadence EDA

Project Code :TVMATO425

Objective

The major contribution of this work is to reduce the delay in Voltage Controlled Oscillators. For reducing the delay, the concept of Negative Skewed Delay (NSD) was designed for VCO.

Abstract

In this project, a Voltage Controlled Ring Oscillator, Current Starved Voltage Controlled Oscillator and Negative Skewed Oscillator are designed with system performance prioritized. Voltage Controlled Oscillator (VCO) is an oscillator whose output signal can be varied over a range, controlled by the input DC voltage. Waveforms and parameters are compared at high performance and Layouts are designed with area under high priority. All the designs are implemented in 45nm technology node in Tanner EDA tool.

Keywords: Ring VCO, Current Starved VCO, Negative Skewed Oscillator, PLL, CMOS Inverter, Low Power.
