ROHM has developed a linear operational amplifier (op amp) – LMR1901YG-M – featuring the lowest current consumption in the industry...
ROHM develops a new op amp that minimizes current consumption
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...
15-bit voltage-to-time ADC for "Proper Function" anemometer linearization
Awhile back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair. The resulting sensor is simple, sensitive, and solid-state, but suffers from a radically nonlinear airspeed response...
Selecting the right inductor current ripple
A switching regulator converts an input voltage to a higher or lower output voltage. For this, an inductor is used to store energy temporarily...
