Abstract: In this project, an all-digital ON-chip process sensor using a ratioed inverter-based ring oscillator is proposed. Two types of the ratioed inverter-based ring oscillators, nMOS and pMOS types are proposed to sense process variation. The nMOS (pMOS)-type ring oscillator is designed to improve its sensitivity to the process variation in the nMOS (pMOS) transistors using the ratioed inverter that consists of only nMOS (pMOS) transistors. A compact process sensor can be realized using only these two types of ring oscillators
