Latest Patents

One of his latest patents is for an averaging flash analog-to-digital converter. This invention utilizes a flash-type ADC that employs only 2^n-m comparators connected to the analog input line to generate an n-bit digital output signal. Each pair of actual comparators is linked in parallel to 2^m pseudocomparators, which provide values representing comparisons of the input signal to respective reference values. The output signals from the actual comparators are combined in different proportions at each pseudocomparator, allowing for the averaging of output signals to produce interstitial comparison values. The ADC can be implemented in BiCMOS technology with a bipolar differential input stage and a CMOS latching comparator. In other embodiments, it can be implemented in CMOS technology, utilizing ratioed transistor widths and capacitors to proportionally divide the output signals. Another significant patent is for an analog-to-digital converter and method of use utilizing charge. This twelve-bit ADC employs two banks of 31 capacitors each, coupled through separate control circuitry to achieve high-frequency operation, ranging from several MHz to about 40 MHz.
