Latest Patents

One of his latest patents is titled "Differential interfaces for power domain crossings." This invention provides techniques for transmitting signals through a differential interface between circuits in different power supply domains. A driver circuit in a first power supply domain converts single-ended signals into differential signals. The driver circuit then transmits the differential signals to a receiver circuit in a second power supply domain. The receiver circuit converts the differential signals back into single-ended signals for transmission to circuit elements in the second power supply domain. This differential interface reduces the transmission of noise between circuit elements in the first power supply domain and circuit elements in the second power supply domain.

Another notable patent is the "Power delivery network calculator tool for printed circuit board capacitors." This method calculates a system power distribution network impedance by treating the impedance as separate elements of the printed circuit board (PCB). An approximation of the power and ground via inductance of the PCB is made based on its configuration. The decoupling capacitors of the PCB are modeled as a parallel combination of inductors, capacitors, and resistors, which is used to calculate the impedance. Additionally, the method calculates an inductance associated with the mounting orientation of the decoupling capacitors. The power and ground planes of the PCB have an associated capacitance and inductance, which is also calculated. The resultant simulated impedance profile illustrates the board configuration impedance over a frequency range.
