Latest Patents

One of his latest patents is the "Curvature Corrected Bandgap Circuit." This invention provides an apparatus and method for correcting temperature variations in a band-gap reference circuit. The apparatus includes a band-gap cell, an IPTAT circuit, a resistor, and a feedback circuit. The band-gap cell is designed to deliver a band-gap voltage, while the resistor circuit connects both the band-gap cell and the IPTAT circuit. The feedback circuit selectively activates the IPTAT circuit, adding an additional correction factor to the temperature response of the band-gap cell, thus providing a second-order curve. The IPTAT circuit can be implemented as a simple transistor that responds to changes in absolute temperature.

Another significant patent is the "Polyfuse Trim Read Cell." This invention utilizes a polysilicon fuse structure in a single-bit memory cell. When the fuse structure is blown, the memory cell can be read, and its stored value is retained as a digital output. Notably, the cell consumes no power in the steady state, making it an efficient solution for memory storage.
