Abstract
A general active switched-capacitor biquad is introduced. The circuit is immune to the various parasitic capacitances and is based on the two-integrator-loop topology. It implements the noninverting forward-Euler and the inverting backward-Euler discrete integrators. The circuit is the most general of its kind and all published biquads and many others can be generated from it.
