Abstract :
A state variable approach to designing a resistive input noninverting differentiator is presented. The differentiator consists of an active integrator and a summer. The upper break frequency where differentiation ceases is tunable by trimming a single resistance. The lower corner frequency where differentiation starts is tunable by varying the RC product of an integrator. The differentiation of high-frequency noise is avoided by switching to amplifier action at high frequencies. The integrator de-emphasizes high-frequency noise
