Abstract :
A transconductor-C filter system is optimized for high frequency and low power operation. The optimization is achieved through systematically optimizing the transconductors in the filter. Theoretical analysis as well as HSPICE simulations are conducted for both transconductor and filter. The results showed that by choosing proper bias conditions, optimum frequency vs. power performance can be obtained
