Suppressing derivatives of selected variables in Verilog-A

摘要

A former scaling technique made it possible to eliminate the effect of the automatically generated derivatives at bipolar non-quasi-static (NQS) modeling in Verilog-A. An alternative technique is proposed here, which makes the derivatives of selected variables zero. The method was verified on the examples of bipolar NQS variants. The confirming results open a new perspective for increasing the flexibility of Verilog-A compact modeling along with the reduction of computational efforts.
