Abstract:
An implantable medical device system having a bus and first and second logic electrical components, said bus extending between said components, said system for generating a logic signal and for minimizing power dissipation within the implantable medical device, the system comprising:means for defining a first potential; a capacitive element associated with the bus and the first potential; N voltage supplies, wherein N>1; N switches corresponding to the N voltage supplies, each switch being operatively coupled between a corresponding one of the N voltage supplies and the capacitive element; a first switch operatively coupled in parallel with the capacitive element between the N switches and the first potential; and a controller operatively coupled to the N switches and to the first switch to control the N switches to generate a ramped logic signal across the capacitive element that is applied to the bus and to either logic electrical component and to control the first switch to reset the voltage on the capacitor to the first potential.
