Graeme Double Integrator

By placing the poles of two Tee networks (R1, C1, R2 & C2, R3, C3) at the same frequency, U1 performs double integration of its  input signal Vin. The gain of the circuit is dependent on the values of the R & C values. For additional information, see “Applications of Operational Amplifiers- Third- generation Techniques” by Jerald G. Graeme. In the absence of system feedback, R4 is used to close the loop to establish a DC operating point. It is not necessary in actual operation. (Circuit is created by Neil P. Albaugh,  TI – Tucson)
