A novel voltage sensing method based on the depen- dence of the operating mode of a circuit on the supply voltage is proposed. The method is applied on an even stage ring oscillator with the inherent property of switching between oscillating and latching modes at certain Vdd levels. A set of techniques used for the analysis and simulation results are presented. Index Terms — voltage sensing, oscillator, dynamical system
