Low Power Positive Edge Triggered Pulse Generater Using Ring Oscillator

Abstract

In this brief, a low power positive edge triggered pulse generator design is presented. The positive edge triggered pulse generator is design with the help of 3-stage ring oscillator. The 3-stage ring oscillator used as a input source to pulse generator. Based on simulation results using 180 nm CMOS technology, the positive edge triggered pulse generator design operates on 1 V for frequency 800 MHz. In addition, a simple analysis of pulse generator allowing estimating the oscillator frequency from the process and transistor parameter values is provided. In the meantime, the performance of power of ring oscillator and pulse generator reduces 50% and 20% respectively.
