Latest Patents
One of his latest patents is titled "System and method for startup bootstrap for internal regulators." This invention involves a regulator circuit designed to protect downstream devices from unregulated voltages during start-up or initialization. The circuit features an operational amplifier that controls a regulator during steady-state operation. Additionally, it includes a switching portion that disconnects the op amp from the voltage regulator upon receiving a reset signal, preventing unregulated voltages from reaching the output node during start-up. A current mirror is utilized to provide an initial voltage reference to the op amp, ensuring a smooth transition to steady-state operation.
Another significant patent is the "System and method for achieving uniform screen brightness within a matrix display." This invention addresses the challenge of producing uniform energy dissipation in display pixels with varying electrical characteristics. It aims to equalize light output and improve yield within a matrix addressable display panel. The system is implemented within a driver circuit that employs current integration. A reference voltage, proportional to the most efficient pixel, is compared to the energy dissipated within a particular pixel during illumination. A current mirror circuit supplies an equivalent current to an integrator circuit, resulting in a rising voltage that is proportional to the energy being dissipated.
