Abstract

A system for minimizing power dissipation within an implantable medical device through use of adiabatic logic is disclosed. The system includes a first and a second sub-circuit of the implantable medical device. An electrical connection interconnects the first and the second sub-circuits, the electrical connection including a capacitive element. Circuitry, which charges the capacitive element of the electrical connection to generate a ramp logic signal, is connected to the capacitive element. The ramp logic signal includes a frequency of less than 500 kilohertz, thereby creating a low frequency, low power system which reduces energy dissipation to the surrounding environment.
