Description

The Negative Supply Rail block represents an ideal negative supply rail. Use this block instead of the Simscape™DC Voltage Source block to define the output voltage relative to the SimscapeElectrical Reference block that must appear in each model.

Note

Do not attach more than one Negative Supply Rail block to any connected line.

Ports

Conserving

Electrical conserving port associated to the negative supply rail negative voltage.

Parameters

expand all

The voltage at the output port relative to the Electrical Reference block ground port.

Model Examples

Differential Pair Amplifier

Differential Pair Amplifier

A differential pair amplifier circuit. The circuit can be used to explore the properties of a differential pair amplifier. The model can be tested using differential and common-mode inputs. The balanced output has zero gain in common-mode provided that the two transistors have identical properties.
