Joachim Neves Rodrigues, Omer Can Akgun, Puneet Acharya, Adolfo de la Calle, Yusuf Leblebici, Viktor Öwall
2010 Lecture Notes in Computer Science  
The architecture of the detector is partially folded to minimize hardware cost. An energy model is applied to evaluate the energy efficiency in the sub-threshold (sub-VT ) domain.  ...  Due to folding, energy efficiency of the circuit is increased by 14.4 % in the sub-VT regime, where the circuit dissipates 3.3 pJ per sample at VDD=0.26 V.  ...  In Sec. 2 the folding scheme of the cardiac event detector is presented. The energy model is presented in Sec. 3. In Sec. 4 the results of the energy dissipation reduction are discussed.  ...
