Latest Patents
One of Griffith's latest patents is a "System and method for recovering from a power supply interruption." This innovative system provides a mechanism for recovering electronic apparatus in response to momentary interruptions in the voltage level of a power supply. The system includes a level detecting circuit that monitors the voltage supplied to the apparatus. It also features internal reference supply circuits that provide necessary voltage and current references for operation. The power cut monitor and reference control circuit ensures that the internal reference supply circuits remain enabled during power interruptions, allowing the apparatus to restart in its pre-interruption state once power is restored.
Another significant patent is the "Comparator circuit and method." This comparator circuit includes transistors with the same threshold voltage and employs a method for comparing input signals. The design features a current mirror coupled to a common electrode differential pair and a feedback circuit. The output currents are modulated to generate positive feedback signals, which control the output state of the comparator circuit while providing hysteresis.
