Title: David Joseph Stoops: Innovator in Low-Power Data Acquisition Systems

Introduction

David Joseph Stoops is a notable inventor based in Lake Forest, CA (US). He has made significant contributions to the field of low-power data acquisition systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and accuracy of sensor interfaces, which are crucial in various applications.

Latest Patents

One of Stoops' latest patents is for a low-power data acquisition system and sensor interface. This innovative sensor interface includes an on-chip relaxation oscillator circuit and a phase-locked loop (PLL) that work together to generate a highly accurate clock signal using low-power components. The system utilizes a photodiode to generate a current signal based on an optical signal that represents sensor data. An analog-to-digital converter (ADC) processes this current signal to produce a digital signal, which is then analyzed by a processor to estimate various environmental and biomedical characteristics, such as temperature and heart rate. Additionally, an amplifier may be included to enhance the photodiode's current signal before it reaches the ADC.

Another significant patent by Stoops is the tri-level digital-to-analog converter. This invention outlines methods, systems, and apparatuses for converting a digital input signal into an analog output signal. The system employs a first delta-sigma modulator to generate a common mode control signal, which is then used by a data delta-sigma modulator to produce a modulated digital input signal. A shuffler processes these signals to create a shuffled digital input signal, which is fed into a digital-to-analog converter (DAC) composed of tri-level unit DAC elements. These elements work together to generate the final analog output signal.
