Abstract

For elliptic lowpass switched capacitor filters designed using the signal flow graph representation of an LCR prototype filter, the letter examines the constraints on the signs of the branches in the signal flow graph, and proposes integrator building blocks which best satisfy these constraints with the minimum introduction of additional sensitivities.
