Latest Patents

One of his latest patents focuses on the "Determination of worst case voltage in a power supply loop." This invention provides various systems, methods, and programs that are embodied in a computer-readable medium for determining the worst-case impedance and voltage of a power supply loop connected to a power input of a die. The method involves measuring the worst-case impedance and calculating a reference voltage based on average current generated at the power supply. Additionally, it measures the maximum change in current at the power input and estimates the worst-case voltage accordingly.

Another significant patent is the "System and method of measuring low impedances." This method involves generating first and second current levels, measuring them, and creating a periodic current waveform. The voltage at various ports in a system is measured multiple times to obtain sets of voltage measurements, which are then averaged. The method also includes generating current levels at different clock frequencies, determining Fourier components of the averaged voltage measurements, and filtering out clock frequency-dependent noises to accurately determine impedance.
