Design of Switched-Capacitor Filters
Capacitors can be scaled in groups that are independent of one another. Such groups generally exist around opamp-based integrators. Furthermore, scaling all the capacitors connected and switched to the input of an opamp leaves the filter transfer function unchanged. Capacitor groups can be scaled individually for noise minimization.
