The paper reviews the application of VLSI in Bio-Medical electronics. It highlights the development of VLSI in micro-electronics such as pacemakers. The concept of VLSI is combined with the advantages of Adiabatic Circuits to develop a power-efficient method for Pacemakers. Basic measurements such as Power consumption, Drive Current and Area of the circuit are tracked. A schematic for reducing the power required to drive the circuit to the stability of a system using Adiabatic Logic is proposed. For this purpose, a simulation is performed highlighting the efficiency of the circuit. Further efficiency improvements for future models and schematics are outlined
