## 3.6 `F`: Current Controlled Current Source

### 3.6.1 Syntax

`F` xxxxxxx n+ n-- ce value
`F` xxxxxxx n+ n-- ce expression
`.CCCS` label n+ n-- ce expression

### 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.
