Design of Temperature Insensitive Ring Oscillator

Abstract

This paper mainly describes a new method to lessen the delay instability introduced to temperature.The Improved Programmable Temperature compensation Devices (IPTCD) are used in the Inverter design to pull up and pull down gates to their respective temperature insensitive operating points, thereby reducing the temperature effect.The delay time uncertainity has been reduced to 87.3% when compared to other inverter techniques with the variation in temperature ranging from-55 • C to-125 • C.we overcame the disadvantages of high P*τ product, low supply voltage and delay time problems in PTCD design proposed earlier. More over, we propose a process variation system to set our IPTCD design temperature insensitive.we have explained how to extend this IPTCD design to ring oscillator in this proposed paper.This helps in many temperature insensitive ring oscillator applications.
