Abstract
A low-corner frequency high pass filter circuit ( ) includes an operational amplifier ( ). The operational amplifier ( ) has an inverting input ( ) and a non-inverting input ( ). A series capacitor ( ) has a first end connected to the non-inverting input ( ) of the operational amplifier ( ). A second end of the series capacitor ( ) is connected to an input signal ( ). A low gain amplifier ( ) has an input connected to an output ( ) of the operational amplifier ( ) and has an output ( ) connected to the non-inverting input ( ) of the operational amplifier ( ). The low gain amplifier ( ) performs the function of large value resistor.
