New STM32H7R/S microcontrollers raise embedded-application performance to new levels for next-generation smart devices in factories, buildings, infrastructure, eHealth...

new improved latching power switch. Part
A new and improved latching power switch. Part 1
04.04.2024 Circuits

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 Proper Function anemometer
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...

This design for a photonic switch needs more than approximately 70 V at the cathode of a duo-lateral optical position-sensing device...

Rotary encoder mates digital potentiometer
Rotary encoder mates with digital potentiometer
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...
