Abstract :
An on-chip filter using monolithic transformer that can be integrated on a Si substrate is presented. The new filter topology has been fabricated using Motorola 0.18 micron copper process. Measurement results show significant improvement in Q of the present design compared to the inductor implementation. The size and Q advantages of the new topology can be useful in cost sensitive consumer products.
