In a DC power supply circuit, changes in load can cause power supply noise. For example, in a digital circuit, when the circuit switches from one state to another, a large peak current will be generat...
I have no idea at all. The limitation is that I have to use 51 series chips, and I only have AT89S52 on hand. If all the possibilities of displaying the pointer on half screen are stored in the on-chi...
I haven't posted for a few days, I've been doing other things :) 2010.5.14 Tested the PWM function, now I'm posting some pictures!! You can set the duty cycle and so on according to the relevant param...
This article of the rookie was originally posted on the blog for a few days. Today, I accidentally found that hellodsp reposted it. Thinking about it, I have been lurking here for two years, especiall...
I made a voltage follower using AD8011 (current feedback type). The voltage signal is a small sine wave. I hope it can have a good following effect within the bandwidth of 80MHz.
The circuit is solder...
