How to make a noise-free infrared obstacle detection module
An obstacle detection unit is an essential part of a variety of projects, such as robotics and security applications. The infrared sensors are widely used for these types of applications...
ROHM develops a new op amp that minimizes current consumption
ROHM has developed a linear operational amplifier (op amp) – LMR1901YG-M – featuring the lowest current consumption in the industry...
Single phase mains cycle skipping controller sans harmonics
In electrical heating applications, resistive heaters are powered through phase angle-controlled SCR/triac circuits to vary the applied voltage/power to maintain the required temperature. Phase angle control produces a lot of harmonics leading to power line disturbances...
Are FinFETs coming to an end?
FinFETs redefined chip design when they came onto the scene more than a decade ago. While these nonplanar transistors are still the unofficial industry standard, they may be nearing the end of their life...
Seeed unveils the compact matter-ready XIAO ESP32C6 dev board
Seeed Studio has launched a new entry in the XIAO family of small form factor microcontroller development boards, built around the Espressif ESP32-C6: the RISC-V XIAO ESP32C6, boasting Wi-Fi 6, Bluetooth 5.3 Low Energy (BLE), and Matter-ready IEEE 802.15.4 connectivity...
Ceramic input capacitors can cause overvoltage transients
A recent trend in the design of portable devices has been to use ceramic capacitors to filter DC/DC converter inputs. Ceramic capacitors are often chosen because of their small size, low equivalent series resistance and high RMS current capability...
A new and improved latching power switch. Part 2
Although adequate for undemanding applications, the circuit suffers from several drawbacks which may limit its suitability...
STMicroelectronics' high-performance microcontrollers pave the way to new innovations in smart home and industrial systems
New STM32H7R/S microcontrollers raise embedded-application performance to new levels for next-generation smart devices in factories, buildings, infrastructure, eHealth...
A new and improved latching power switch. Part 1
A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader feedback. Amongst other comments, readers questioned whether it would be possible to adapt the circuit to provide (a) a cross-coupled arrangement...
