FILTER APPLICATIONS USING DUAL MODE DXCCII

Abstract

From the last two decades there has been a revolutionary change in the use of CMOS technology is a popular choice to implement filters, multipliers, oscillators, and several other important building blocks for many applications. In the field of electric and electronic engineering, filters play an important role and have been widely applied in various aspects such as communications systems, instrumentation, measurement and signal processing, etc. In this present thesis three filters have been designed using both current and voltage mode. The Voltage-mode filter follow the voltage at the load which is driven by a voltage supply ,in the same way current mode filters execute with the condition of current as a source for the working of filter. When a user get both the modes available to him then any mode can be used as per requirement of the user eliminating the drawbacks of the other mode.
