Latest Patents
One of his latest patents is titled "Amplifier having a symmetrical output characteristic." This invention describes a symmetrical amplifier that includes a current mirror circuit and a current splitting circuit. The current splitting circuit is designed to split an input signal based on its polarity. Negative input currents are directed to the current mirror circuit, which controls the output current applied to a first current amplifier circuit. To ensure symmetrical operation, positive input currents are applied to a second current amplifier circuit, which mirrors the first. Both circuits operate into a common load, enhancing the amplifier's performance.
Another significant patent is for a "Semiconductor device having a bipolar transistor with emitter series." This invention involves a semiconductor body that contains a bipolar transistor with parallel transistor structures, each having different emitter series resistances. The design allows for various active emitter regions and contact regions, optimizing the performance of the transistor without altering the emitter zone geometry.
