Title: Second order differential high frequency filter
Inventor: WU CHIEN-PING
IPC: H03H11/04
Filed: 1997-09-04
Abstract: The second order differential high frequency filter includes a differential amplifier circuit and a feedback processing circuit. The differential amplifier circuit includes a first op-amp (OP1) and four resistances (R3-R6), where R4/R3 = R6/R5. When the input voltages (V1,V2) are separately sent through R5 and R3 and into the inverting and non-inverting inputs of the first op-amp, the output of the first op-amp is fed through the resistance (R6) and fed back to the inverting input of the first op-amp. The feedback processing circuit includes a second op-amp (OP2), two resistances (R1,R2) and two serial capacitors (C1,C2). The output of the second op-amp is fed into its inverting input and the non-inverting input is grounded. The second op-amp output is fed through the two serial capacitors and into the inverting input of the second op-amp. Simultaneously, the other output is fed through the resistance R4 into the non-inverting input of the first op-amp magnifier to form feedback in which the two serial capacitors are coupled through the resistance R2 to ground.
