Abstract

A highly power supply independent Ring Oscillator architecture is proposed in this paper. The proposed architecture is achieved using the advantages of best previous techniques. Making use of opposite characteristics of the delay cells along with power supply isolation and self-biasing have resulted in a nearly 1% sensitivity; a record better than all previous architectures. To accomplish such robustness, different delay stages with different characteristics have been used in the proposed architecture. Simulations based on 0.5µm CMOS technology confirm robustness of the proposal.
