Abstract :
This work presents a novel technique for the design of continuous time analog filters with high dynamic range and low power dissipation. The essence of the method is to break up the required dynamic range of the filter in smaller ranges, and utilize separate filters in each one of them. This is done in such a way that the output is not disturbed whenever a different filter takes over. Very serious power dissipation and chip area savings will be shown to result from this technique
