The proposed low-pass filter contains an operational amplifier with resistive feedback and a T-type element, which is connected to the inverting input of the amplifier. The T-type element contains two resistors, which are connected in series, and a piezoelectric element, which is inserted between the common connection point of the resistors and thecommon point of the filter circuit. The feedback resistor is inserted between the output of the amplifier and the common connection point of the resistors of the T-type element. The resistor and piezoelectric element of the T-type element that are connected to the inverting input of the amplifier form an analog integrator.
