Abstract
Official abstract text for this publication.
Some embodiments of the present disclosure relate to a sensor interface module. The sensor interface module includes a comparator having a first comparator input, a second comparator input, and a comparator output. A current- or voltage-control element has a control terminal coupled to the comparator output and also has an output configured to deliver a modulated current or modulated voltage signal to an output of the sensor interface module. A first feedback path couples the output of the current- or voltage-control element to the first comparator input. A summation element has a first summation input, a second summation input, and a summation output, wherein the summation output is coupled to the second comparator input. A supply voltage module provides a supply voltage signal to the first summation input. A second feedback path couples the comparator output to the second summation input.
First claim
Opening claim text (preview).
What is claimed is: 1. A sensor interface module comprising; a comparator having a first comparator input, a second comparator input, and a comparator output; a current- or voltage-control element having a control terminal coupled to the comparator output and having an output configured to deliver a modulated current or modulated voltage signal to an output of the sensor interface module; a first feedback path that provides the modulated current or voltage signal from the outp…
