Latest Patents

Peirce holds a patent for a voltage level shifting circuit. This integrated level shifter circuit converts an input signal with a first voltage potential to an output signal with a second voltage potential. The circuit enables operation between different sections of an integrated circuit that operate with varying supply voltages. The design includes two transistors and a voltage divider circuit with two resistors in series. The resistor values are carefully selected to achieve a desired output voltage at a node between the resistors. This innovative approach reduces a full 0.9-volt diode drop to yield a level shift that is a fraction of a diode drop. Additionally, a capacitor in parallel with the resistor enhances the speed and bandwidth of the level shifter, making it highly effective for AC signals.
