Frequency domain methods of extracting equivalent series resistance (ESR) and equivalent series capacitance (ESC) for on-die decoupling capacitors using spice-like simulators are briefly reviewed. A concise method is then proposed for converting the frequency domain equivalent ESR and ESC to an approximate broadband equivalent circuit which can be readily used in time domain simulations. The method is validated using empirical measurements of relevant integrated circuits.
