Title: Innovations by Roger W Fuller
Introduction
Roger W Fuller is an accomplished inventor based in Scotts Valley, CA (US). He holds 2 patents that showcase his expertise in electronic circuit design and innovation. His contributions have significantly impacted the field of integrated circuits and power supply systems.
Latest Patents
One of his latest patents is the "CMOS amplifier/driver stage with output disable feature." This invention relates to an output circuit capable of producing an output signal that can be disabled, leaving the output terminal in a high impedance state. This allows for external driving of the output terminal to a voltage significantly outside the bounds of the output circuit power supply. The circuit includes an MOS transistor and a second transistor, which work together to ensure that the output terminal can be driven beyond the limits of the power supply voltages. This innovation is particularly useful in 'wired-or' configurations, allowing operation with multiple power supplies or even without a power supply.
Another notable patent is the "Integrated dual charge pump power supply including power down feature." This monolithic integrated circuit converts a unipolar supply voltage to a bipolar supply voltage of greater magnitude. The design incorporates a series of MOS switches and capacitors to achieve the desired voltage conversion while ensuring correct start-up conditions. This circuit also includes gain reduction devices to prevent latch-up, enhancing the reliability of the power supply system.
