Seeed unveils the compact matter-ready XIAO ESP32C6 dev board
04.09.2024 News

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
Ceramic input capacitors can cause overvoltage transients
04.08.2024 Articles

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...

15-bit voltage-to-time ADC for "Proper Function" anemometer linearization
04.03.2024 Circuits

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...

03.29.2024 Circuits

In developing electronic systems, designers look for products or ideas that may benefit from the better performance, smaller size, lower cost, and improved reliability that an IC can offer. Toward that end, the digital potentiometer emerged as an alternative to its mechanical counterpart, the mechanical potentiometer...

Charge pump halves voltage double current
Charge pump halves voltage to double current "efficiency"
03.27.2024 Circuits

Capacitor type charge pumps are a well-known, simple, efficient, cost-effective method for inverting and multiplying voltage supply rails. Perhaps less well known, however, is that they also work just as well for dividing voltage...
