Description

[Picture]

The Metal Oxide Semiconductor Field Effect Transistor is a semiconductor switch that is controlled via the external gate. It conducts a current from drain to source (or vice-versa) only if the gate signal is not zero.

Parameters and Dialog Box

Width
The width of the component. This affects both the width of the electrical ports and the width of the gate input signal. The default is 1.

Each of the following parameters may either be a scalar or a vector with the width of the component:

On-resistance
The resistance Ron of the conducting device, in ohms (_O_). The default is 0.
Initial conductivity
Initial conduction state of the MOSFET. The MOSFET is initially blocking if the parameter evaluates to zero, otherwise it is conducting.

Probe Signals

MOSFET voltage
The voltage measured between drain and source.
MOSFET current
The current through the MOSFET flowing from drain to source.
MOSFET conductivity
Conduction state of the internal switch. The signal outputs 0 when the MOSFET is blocking, and 1 when it is conducting.
