F — Current-Controlled Current Source (CCCS)

A current-controlled current source produces an output current proportional to a controlling current (measured through a voltage source).

Syntax

Linear

F<name> <out+> <out-> <Vcontrol> <gain> [M=<m>]

Polynomial

F<name> <out+> <out-> POLY(<dimension>) <Vcontrols...> <coefficients...>
Parameter Description
out+, out- Output nodes (current flows from out+ to out-)
Vcontrol Name of a voltage source sensing the control current
gain Current gain (Iout = gain × Ictrl)
M=m Multiplier

Examples

* Simple current mirror with gain 2
F1 OUT 0 Vsense 2

* Requires a 0V sense source in the control path
Vsense CTRL_A CTRL_B 0

Notes

  • The controlling current is the current through the named voltage source.
  • A 0V voltage source is commonly used as a current sensor (ammeter).
