Sensors of all types have come a long way in the last few years and tend to be more accurate and more stable than their predecessors. These sensors are not always simple to use. Designers of ...

Accurate signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer- electronic equipment also need to ...

We’re all familiar with the general idea of a filter: it removes something that we don’t want from something we do want. Coffee filters that pass the liquid coffee but retain the grounds or air ...

A look at the design of traditional ADC front ends. How to simplify the input drive of CTSD ADCs. Simplifying reference and reference-drive designs. In this article, we will use the terms “sensor” or ...

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...

Melexis has brought out a dual-input inductive sensor integrated circuit (IC). The device simultaneously processes signals from two sets of coils to compute differential or vernier angles on-chip.

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

A traffic signal sensor in Portland. Welcome to our newest column: Bike Science with Shawn Small One of the more frustrating aspects of cycling in an urban environment is not being able to trigger a ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...
