Apparatus and method for electrical stability compensation

A method for electrical stability compensation comprising:

• providing a programming phase during which:
• a programming signal is provided to a gate of the drive transistor;
• and
• a charge is released from a first variable capacitor;
• and
• providing a driving phase during which:
• a charge is drawn from a gate of the drive transistor by the first variable capacitor.

An apparatus for electrical stability compensation comprising:

• a drive transistor connecting a power supply to a load;
• a first variable capacitor comprising a transistor in which a source and a drain to provide a gate and a source, wherein the gate of the first variable capacitor is connected to the gate of the drive transistor and the first variable capacitor is configured to draw a charge from the gate of the drive transistor during a driving phase for the load;
• a second variable capacitor comprising a transistor in which a source and a drain to provide a gate and a source, wherein the gate of the second variable capacitor is connected to the gate of the drive transistor and the variable capacitor is configured to inject a charge to the gate of the drive transistor during the driving phase;
• and
• a switch transistor for controlling a connection between a programming signal source and a gate of the drive transistor.
