Circuit Function and AdvantagesThis circuit is used to measure RF power from 1 MHz to 8 GHz over a range of approximately 60 dB. The measurement result is provided as a digital code at the output of a...
There are some differences between the standard STM32 library and the HAL library. The code produced by STM32 CUBE uses the HAL library. Those who used the standard library before may need correspondi...
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]

Learning single-chip microcomputers is a very practical process. At present, single-chip microcomputer laboratories are basically built with hardware simulation equipment. Due to...[Details]
Digital storage oscilloscopes (
DSOs
) are now on almost every engineer's bench. However, many DSOs are still paired with analog real-time (ART) oscilloscopes. Why?
This is because both p...[Details]
One product we are all familiar with as consumers is the traditional incandescent flashlight, which typically has a very basic circuit design: batteries, an incandescent bulb, an on-off switch,...[Details]
For white LEDs
with a forward voltage of 3.5 to 4.2V (at 20mA),
a boost converter is usually required. A charge pump (such as MAX682 to MAX684) can be used together with MAX1916 to form
