STMicroelectronics' high-performance microcontrollers pave the way to new innovations in smart home and industrial systems
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...
Virtual-zener circuit simplifies high-voltage interface
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 with digital potentiometer
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 to double current "efficiency"
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...
Add a grounded-switch feature for TOPSwitch on/off control
The Power Integrations TOPSwitch family of integrated flyback-regulator ICs provides exceptional performance in small, low-pin-count packages. For the lowest-pin-count packages, the multifunction, or M, pin serves multiple purposes...
Auxiliary supply requirements for SiC/GaN gate driver systems
Wide bandgap power semiconductor devices like Silicon Carbide (SiC) MOSFETs are enjoying growing popularity in many modern power electronic applications like E-mobility and renewable energy. Their extremely fast switching speed capability helps to increase efficiency...
Supersized log-scale audio meter
At the end of the DI for a Simple log-scale audio meter I promised to show how to upgrade it to work better...
