Authors: Abozeid, K.M.; Aboudina, M.M.; Khalil, A.H.
Journal: ICENCO 2015
Description:
In this paper we present an offset cancellation technique for a comparator used in SAR (successive approximation register) analog to digital converter improving the signal to noise ratio of the whole system with minimum power consumption at the expense of complexity of the system. An 8-bit SAR ADC is presented with power consumption 22nW, ENOB = 7.051 and SNR = 47.11 dB. All simulations are done under clock frequency = 100 kHz and a supply voltage 1V.

Different configurations for dynamic latched comparators used in ultra low power Analog to Digital converters
Authors: Abozeid, K.M.; Aboudina, M.M.; Khalil, A.H.
Journal: ICET 2014
Description:
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.
