Abstract :
This paper presents a comparison in the consumed power between different configurations of dynamic latched comparator used in low power Analog to Digital (A/D) converters especially the successive approximation register (SAR) which is used in many Electrical, Radio-frequency identification (RFID) and biomedical applications. This comparison is in architecture, consumed power and propagation time delay. The comparison is done under constant input referred offset.
