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 Simscape Electrical Reference block that must appear in each model.
Note
Do not attach more than one Negative Supply Rail block to any connected line.
Examples
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.
