Abstract
This paper explains the design of a Universal (Low, High, Band and Notch)
Second-Order Filter using switched capacitor (SC) technique. The design depends
on the crystal oscillator circuit that generates two non-overlapping clocks by
making full use of the two independent comparators of the LM741. The oscillator
circuit is used to drive a switched-capacitor integrator which is used in the design
of the universal second order filter. The circuit is performed as a single IC
(Integrated circuit) which can be used for different standard applications. The
proposed IC design differs than other IC's such as MF10 by adding the notch filter
to this design for used in wide band of applications. The design is simulated using
MultiSim 9 program.
