Title: The Innovative Mind of Brooks A. Cummings

Introduction

Brooks A. Cummings, an accomplished inventor based in Chittenden, Vermont, has made significant contributions to the field of analog to digital conversion technology. With two patents to his name, Cummings is known for his ingenious solutions to improve the functionality and reliability of ADC systems.

Latest Patents

Cummings' latest patents focus on enhancing the testing mechanisms of analog to digital converters. The first patent, titled "Built-in self-test for analog to digital converter," introduces an on-chip test circuit that includes a waveform generator to create a known arbitrary waveform. This innovative design allows a switch to connect the generator to the ADC in test mode, enabling the ADC to produce a defined sequence of digital codes. A unique signature register then compresses this sequence into a single signature that effectively represents the ADC's entire digital output sequence, ensuring tests on ADC monotonicity, linearity, and validation of missing codes.

The second patent, "Built-in self-test method and structure for analog to digital converter," provides a structured approach for testing an A to D converter made up of multiple discrete components. The method divides the circuit into segments for targeted evaluation. Each segment's component values are tested and compared, generating an output signal that represents the differences, thus allowing comprehensive testing through a systematic approach.
