Tuning space mapping with tuning exponent of ABCD-matrix

Tuning space mapping (TSM) with tuning exponent parameter of ABCD-Matrix is proposed and verified. A section of design interest in the electromagnetic (EM) model is replaced by ‘n’ pieces cascaded ABCD-Matrixes, and each ABCD-Matrix is the EM-simulated ABCD-parameter of pre-assigned cell circuit (PCC). Finally the optimal exponent parameter of ABCD-Matrix is transferred to original optimization variables. The proposed TSM not only has the advantages of circuit tuning element-less (CTEL) TSM in prior art but also clears the number range limitation that the tuning parameter must be positive for tuning in CTEL TSM. The proposed method has the second minimal specification error and lowest simulation time comparing with other TSM methods. Verification examples and comparisons are also implemented.
