Patents by Inventor Hock Poh Lim

Hock Poh Lim has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Adjustable internal gate resistor
    Patent number: 9413352
    Abstract: The disclosure describes a method for controlling a voltage that is applied to a voltage controlled circuit element. In one example, the method includes controlling, by a semiconductor light source, a resistance value of a photoresistor coupled to a voltage controlled circuit element. The method includes applying, by a gate driver and via the photoresistor, a voltage to the voltage controlled circuit element. The method further includes controlling the voltage applied to the voltage controlled circuit element in order to control a current through the voltage controlled circuit element. In some examples, controlling the voltage applied to the voltage controlled circuit element may be accomplished by controlling the resistance value of the photoresistor in order to control a voltage drop across the photoresistor. Circuits that implement the method are also described.
