Voltage Controlled Voltage Source Hspice
This can be modelled using a voltage controlled current source with voltage controlled by table based voltage controlled current source.
Voltage controlled voltage source hspice. If the simulation continues beyond the last pair s time then that pair s voltage will be maintained for the remainder of the simulation. Spice netlist template format designator 3 4 1 2 gain. A simple addition to the above resistor model gives you a voltage controlled resistor. Using sources and stimuli star hspice independent source functions star hspice manual release 1998 2 5 7 v1 initial value of the voltage or current before the pulse onset v2 pulse plateau value td delay time in seconds from the beginning of transient interval to the first onset ramp default 0 0 and for td 0 0 td 0 0 is used as well.

Subckt tablecap 1 2 params. The voltage at times between corners is the linear interpolation of the voltage at the corners. Special function 31. All you need is a controlling voltage to multiply the resistor value.
If the first pair s time is not zero then the source s dc voltage will be used as the initial value. Don t leave it float neither connect it to a voltage source directly. Here s a subcircuit for this device subckt vc res1 10k 1 2 4 5 eres 1 3 value i vsense 10k v 4 5 vsense 3 2 dc 0v ends. Parameters definable at component level the following component level parameters are definable for this model type and are listed on the parameters tab of the sim model dialog.
Anyone have any idea how it works and what are. Hi i have found the voltage controlled voltage source vcvs voltage controlled current source vccs in advanced design system simulation and trying to understand how it works in modeling a circuit.

You can connect node 2 to a current source or to a voltage source by a resistor. Computes cjo from c4 hsense.
