In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

1-08-2017 | The focus of this article is to help solve some key design issues when using photodiodes for precision measurements. It discusses how to int ...

Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

Building a photodetector that works across a range of applications does not have to be complicated. In this post, we will break down a universal design concept that is flexible, practical, and ready ...

Abstract: Wavelength sensing using ultra low cost electronic circuits is a prime demand in numerous industrial systems. This work proposes an approach towards wavelength sensing in fiber optic devices ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

Join us for an exciting hands-on workshop where you'll take your first steps into the world of microcontrollers and electronic circuits. These circuits are all around us, even if we don't realize it.

Abstract: This paper presents ultra-low power photoplethysmography (PPG) readout circuits. The proposed system architecture uses a current buffer between the photodiode (PD) and the transimpedance ...
