Abstract :
The paper presents a new actively compensated filter, which is a modified form of an existing active filter. Design guidelines are developed to eliminate its first order sensitivity and to reduce the second order sensitivity through optimization. PSPICE simulations and experimental results are provided to prove the theoretical predictions. Simulation and experimental results also show that, by choosing proper op. amps., the new circuit can be used to realize filters at very high frequencies in the order of a few hundreds of kHz
