Abstract
An apparatus includes a slew rate regulation circuit, a plurality of switches and a controller circuit. The controller circuit controls the plurality of switches to decouple a first source supply voltage from a supply rail; control the plurality of switches to couple a second source supply voltage to the supply rail to replace the first source supply voltage with the second source supply voltage; and control the slew rate regulation circuit to regulate a slew rate of a voltage of the supply rail during a time interval in which the first source supply voltage is being replaced with the second source supply voltage.
