A dual-mode wavelet based R-wave detector using single-Vt for leakage reduction [cardiac pacemaker applications]

Abstract
This paper presents the implementation of a dual mode wavelet based R-wave detector for cardiac pacemakers. A previously published R-wave detector was developed for a noisy environment. This detector has been supplemented with a noise detector that operates in supervision mode, and automatically activates/deactivates 2/3 of the detector hardware without performance degradation. The noise detection is based on zero-crossing rate computation. A low clock frequency results in leakage power being the main power source. Power estimation shows that the power consumption in an ASIC is reduced by 67% when using gate-transistors in the power supply rails. The detector has been synthesized in 0.13 μm low-leakage CMOS technology
