Pull requests help you collaborate on code with other people. As pull requests are created, they’ll appear here in a searchable and filterable list. To get started, you should create a pull request.

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Today, phone-connected front-door cameras and comms systems are ubiquitous. But they weren't as common just a few years ago. Here's a DIY smart doorbell design from 2016 for engineers and electronics ...

Abstract: This work presents a read-out amplifier for capacitive sensors, in particular for MEMS microphones, based on a current-feedback topology. This architecture allows for an extensive gain range ...

Abstract: In the last years several ultra-low voltage (ULV) operational transconductance amplifiers (OTAs) with supply voltages below 0.5V have been proposed in the literature. To achieve high gain, ...

Reliable off-grid communication has always been a challenge for hobbyists, makers, and outdoor explorers. Whether you’re hiking deep in the mountains, setting up a temporary field station, or working ...

Manufactured on a GaAs process, the QPA9510 RF power amplifier from Qorvo covers a frequency range of 100 MHz to 1 GHz. It delivers +35 dBm P1dB output and up to 34 dB gain, with on-chip analog gain ...

ROHM Semiconductor was among the key players that exhibited at electronica India 2025. The company’s Group Manager - Technical Centre, Balaji Karthic, while giving us an overview, called attention to ...
