All-pass filters (including first-order all-pass filters and second-order all-pass filters) require only one op amp. All-pass filters are one of many discrete circuits described in a series of mini-gu
The schematic diagram of the environmental sensor has been completed before. This time, the main focus is on drawing the device package and PCB.
There is nothing special about the device package. You
Hello everyone, this is my first post, hope you can help me. Thank you! I recently used a 5G WIFI module, which has three segments corresponding to three PAs in the frequency band of 5180 to 5885MHz,
I want to make an automatic gain adjustment amplifier circuit. The original circuit diagram looks like this, but the gain of our simulation test results does not correspond. What is the problem? Pleas
