Analysis of Low Power Low Kickback noise Dynamic Comparators in Pacemakers


Objectives: The main objective of this work is to explore and investigate the significance of power dissipation and kickback noise in the design of dynamic comparators used in cardiac pacemakers. Methods/Statistics: In this paper a power and noise efficient dynamic comparators are designed for cardiac pacemakers based on conventional dynamic comparators. Results/Findings: It is shown that the dual rail dynamic comparator suffers from low kickback noise but has more power dissipation and vice versa in case of balanced dynamic comparator. From the results it can be noted that either power or kickback noise can be minimized at a time. Application: Pacemakers are cardiac implantable medical devices used to boost up the heart rate. For such devices low power consumption is very vital. Dynamic comparators are power hungry and decision making devices in pacemakers.
