A stable inverting integrator with an extended high-frequency range

A stable inverting integrator is described. The integrator is obtained by inverting the transfer function of a passive RC differentiator. The integrator uses one operational amplifier. The resulting integrator has a built-in zero that could extend its high-frequency range of operation considerably b...

Description
Summary:A stable inverting integrator is described. The integrator is obtained by inverting the transfer function of a passive RC differentiator. The integrator uses one operational amplifier. The resulting integrator has a built-in zero that could extend its high-frequency range of operation considerably beyond that of the Miller integrator. Experimental and simulation results verify the feasibility of the basic concept and the proposed circuit.
