What is the reason for the uneven duty cycle waveform of the flyback power supply?
The flyback power supply circuit is made, with an input of 90V~265v and an output of 15V2A. The magnetic core EI30Ae=...
As shown in the figure below, I want to add a PGA (Programmable Gain Amplifier) to the front end of a high-bit ADC. I see that the noise of the off-the-shelf PGA is usually quite high. I don't know mu...
