    The Role of AC Capacitors in High Speed Circuits

    Aug , 18 2023
    1、Introduction For low-frequency circuits, resistors and capacitors can be analyzed as ideal devices. However, in high-frequency circuits, these two devices will not be "ideal". Today, our main discussion is about the issue of AC capacitors, which are commonly known as AC coupling capacitors. Their main function is to filter out the DC component of the signal, which is symmetrical about the X-axis...
