Nexxim Simulator > Voltage-Controlled Voltage Source, LaPlace
VCVS LaPlace Netlist FormatThe voltage-controlled voltage source with LaPlace transfer function has the following format: Exxxx out+ out- LAPLACE in+ in- a0[,] ... aN / b0[,] ...bD [SCALE=val] [TC1=val] [TC2=val] out+ is the positive node and out- is the negative node of the current source. The entry LAPLACE selects the E element LaPlace transfer function type. in+ and in- are the positive and negative nodes for the control voltage. The division symbol (/) in the instance line is required syntax.
The function of the device is expressed as: The transfer function H(s) is the ratio of two polynomials in the complex variable s. H(s) is specified by giving the coefficients of the transfer function polynomials: The coefficients (a0 ... aN) specify the numerator polynomial of the ratio. The coefficients (b0 ... bD specify the denominator polynomial. The subscripts N and D represent the order of the numerator and denominator respectively. The first coefficients in both numerator and denominator (a0 and b0) are constants, which must be specified even if they are zero. Thus, leading zeros are significant. In addition, intermediate zero-valued coefficients must be explicitly supplied in order to have the non-zero coefficients applied to the correct powers of s. Trailing zeros are not significant, and are automatically removed. For example, to specify the following transfer function (where coefficient a1=0): The netlist would contain the following statement: Eex1 out gnd LAPLACE in gnd 1, 0, 2 / 1, 1, 3
