Latest Patents

One of Sumant Bapat's latest patents is titled "Data directed scrambling to improve signal-to-noise ratio." This invention provides methods and systems for performing binary data conversion in digital-to-analog converters (DACs) that utilize sigma-delta modulators. The patent involves data directed scrambling (DDS) algorithms that effectively shape element mismatch errors to first-order shaped wideband noise. The method begins with receiving binary data, which includes both positive and negative binary data. A DDS unit then converts this binary data into binary thermometer code data by selectively assigning logic ones in a data array based on the received binary data. The method also includes circularly shifting pointers within the array to optimize data handling.

Another significant patent by Bapat is "Apparatus and method including an efficient data transfer for analog to digital converter testing." This invention aims to reduce the production test time of semiconductor devices. The described test system includes a workstation, a handling device, a test body, and a test mainframe, all linked by a communication channel for transferring control signals and data. The test mainframe calculates the number of m-bit packets that can be transferred simultaneously, allowing for efficient data processing and operability assessment of the devices.
