Here the violate line shows us the traditional passive High pass RC filter we seen in previous tutorial. This is the image of Active High pass filter. Here is the Simple High Pass Filter Design:. Let’s Explore further and understand what is special about it:. Also, the voltage gain is largely dependable on the frequency of the signal and the input voltage of the op-amp and how much gain is applied in that op-amp. This is a small list about generic op-amp and there voltage gain. Let’s explore few common op-amps open-loop Dc voltage gain. That means the maximum frequency will pass depending on the gain of the amplifier and the open-loop characteristic of the op-amp. But in the practical scenario it highly depends on components and other factors, here in the case of active high pass filter, the op-amp bandwidth is the main limitation of active high pass filter.

In passive high pass filter, the frequency response is infinite. Changing the amplifier configuration we can also form different types of high pass filter, inverted or non-inverted or unity gain active high pass filter.įor the sake of simplicity, time effectiveness and also the growing technologies in op-amp design, generally an op-amp is used for Active Filter design. If we add an Amplifier across passive high pass filter, we can easily create Active high pass filter. We learned in the previous tutorial about passive high pass filter that its work without any outer interruption or active response. Same as like passive low pass filter, passive high pass filter works with passive components, Resistor and Capacitor. Let’s explore what is an Active High Pass Filter. Previously we described about Passive High Pass Filter and Active Low Pass Filter, now it is time for Active High pass filter.
