摘要：
We apply "space-mapping" optimization for design centering high-frequency integrated continuous-time filters. By appropriately choosing the coarse model, a significant simplification of the space mapping technique is possible, since the coarse model design space is almost a translated version of the fine model design space. Graphical intuition is given for the simplified technique. A design example of a fifth-order 71.4-500-MHz constant-C scaled G(m)-C Chebyshev ladder filter is presented. Measurement results from fabricated ICs are given.
