Latest Patents

Aulagnier's latest patents include groundbreaking technologies that enhance the performance and reliability of electronic systems. One of his notable inventions is a patent for high-side gate drivers for fixed voltage rails. This innovation provides high-side gate driver circuits designed to control the operation of high-side power transistors without the need for external bootstrap capacitors. The design includes three sections: a pull-up section, a first pull-down section, and a second pull-down or Miller clamp section. Additionally, these gate drivers can incorporate a charge pump circuit, effectively eliminating the need for bootstrap capacitors and related circuitry.

Another significant patent focuses on a capacitive isolator that features common mode noise suppression. This invention outlines methods and apparatus for capacitively isolated communication channels that effectively suppress common mode noise. In this design, a driver on the first circuit transmits a data signal to a receiver on the second circuit. A common mode suppression circuit is integrated into the second circuit, which detects common mode movement signals caused by noise pulses and generates a corresponding output signal to maintain current levels across a resistor network, thereby suppressing common mode noise.
