Abstract
Aspects of the present invention include a method, apparatus and device for generating a power on reset (POR) signal in relation to the crossing point of two currents wherein at least one current is a quadratic function and the other is a logarithmic function, where each has a mathematical correlation to a function of the power supply voltage.
