Abstract :
In Switched-capacitor (SC) filter circuits the accuracy of capacitance ratio is of prime importance. A slight variation in the capacitance ratios can affect the performance of filter greatly. The values of fabricated components depend on many fabrication processes. This tool calculates the dimensions of capacitor such that the ratio of capacitance remains nearly same even though there are fabrication errors in capacitances. The results are verified by the post layout SPICE simulations.
