  Abstract

Viterbi decoders are widely used for communication and high-density storage devices. An add-compare-select(ACS) unit has been an active research area for a long time because it is the most critical component in determining the operation speed and power-consumption of the Viterbi decoder. We propose a new comparator which is faster and consumes less power than existing ones. We also used the new comparator for a Viterbi decoder and our simulations results show the Viterbi decoder outperforms existing ones at least 20% in its operating speed.
