Latest Patents
Roy S Kaller holds a patent for a two-step subranging analog-to-digital converter. This invention features a biasing architecture that utilizes a single string of transistor current sources. These sources generate the reference digital-to-analog converter (DAC) bit currents, the low-resolution flash ADC reference ladder voltage, and the ADC bipolar offset voltage. The design ensures high precision and tracking over process and temperature by constructing the reference DAC resistors and other components from the same material and physical construction. The low-resolution flash ADC is implemented as a two-step parallel subranging ADC, which includes both most-significant-bit and least-significant-bit reference ladders. Additionally, a shunt resistor across the least-significant-bit reference ladder allows for direct series connection to the most-significant-bit reference ladder, enhancing the tracking of reference voltages. A bias current compensation resistor network is also included to mitigate input bias current errors.
