Abstract
A system includes a first power supply line that is associated with a first voltage level and a second power supply line that is associated with a second voltage level. A power supply is coupled to the first and second power lines to establish a first voltage of the first power supply line near the first voltage level and a second voltage of the second power supply line near the second voltage level. The power supply has a response during a time period after the activation or deactivation of the power supply in which the power supply does not maintain a difference between the first and second voltages within a predefined range. The system includes a circuit that is coupled to the first and second power supply lines to maintain the difference between the first and second voltages within the predefined range during the time period.
