A high-pass filter is a circuit that uses the properties of a resistor and capacitor to filter specified high frequencies from the input side to the output side. In the event of a capacitor failure, ...

Current Mirror The circuit is used to copy the flow of current in one active device and controlling the flow of current in another device by maintaining the output current stable instead of loading ...

Creating higher-order high-pass filters Now that since we have both first-order and second-order circuits which provide high-pass functions without adding anything in the forward-path gain block, we ...
