Title: The Innovations of William C. Black
Introduction
William C. Black is a notable inventor based in Cedar Rapids, IA (US). He has made significant contributions to the field of analog-to-digital conversion technology. With a total of 3 patents to his name, Black's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is the "Untrimmed 12 bit monotonic all capacitive A to D converter." This invention discloses an M-bit all-capacitive analog-to-digital (A/D) converter that includes 2.sup.N switched capacitors of substantially identical capacitance. These capacitors are utilized to determine the N most significant bits. Each capacitor has one terminal connected to a common node, while its other terminal is switchable to either ground or a positive reference voltage. At the beginning of a conversion cycle, the common node reflects a sampled analog input voltage. A first group of 2.sup.N-1 capacitors is switched to ground, and a second group is switched to the positive reference voltage. Selected capacitors from one of the groups are then sequentially switched to drive the common node voltage to ground. Additionally, Black has developed a method for converting analog signals to digital signals using parallel capacitive elements of substantially identical capacitance.
Another significant patent is related to "Multiple channel analog-to-digital converters." This arrangement aims to reduce error in an interleaved analog-to-digital signal conversion system. The design provides matching and adjustment certainty, which serves as the foundation for error reduction.
