3.6  F: Current Controlled Current Source

3.6.1  Syntax

Device

Fxxxxxxx n+ n– ce value
Fxxxxxxx n+ n– ce expression
.CCCS label n+ n– ce expression

Model (optional)

.model mname TABLE {args}

3.6.2  Purpose

Current controlled current source, or current gain block.

3.6.3  Comments

N+ and n– are the positive and negative element (output) nodes, respectively. Current flow is from the positive node, through the source, to the negative node. Ce is the name of an element through which the controlling current flows. The direction of positive controlling current is from the positive node, through the element, to the negative node of ce. Value is the current gain.

The controlling element can be any simple two terminal element. Unlike SPICE, it does not need to be a voltage source.

You may specify the value in any of these forms:
  1. A simple value. This is the current gain.

  2. An expression, as described in the behavioral modeling chapter. The expression can specify the output current as a function of input current, or the current gain as a function of time.

  3. A model, as described in the behavioral modeling chapter. The table model describes a table of output current vs. input current.

3.6.4  Probes

The standard probes for all basic elements are all available. See the print command for documentation.
