A Novel Design of Industrial Reconfigurable CDC Karim M. Abozeid, Hassan Mostafa, A. H. Khalil, Mohamed Refky Chips, 2026 This paper presents a novel design for a reconfigurable CDC as a multiplexed sensor fusion that converts three analog signals into digital output bits with different resolutions. The proposed reconfigurable CDC design uses the SAR technique that introduces a small chip area and low power consumption. The proposed novel CDC introduces reconfigurability by using a switching capacitive DAC that solves the problem of converting more than one analog signal with a single converter to a different number of output bits, giving better performance than previous designs. In this paper, three analog signals are used (as a case study) in a weather station to be converted. These signals are temperature, pressure, and humidity that are sensed using the BME-280 Bosch sensor. All CDC specifications are measured for each reconfigured number of output bits. The used supply voltage is 1.0 V, and the sampling frequency is 100 kHz. The 12-bit resolution consumes 2.54 µW, ENOB is 11.47 bits, and SNR equals 73.4 dB. The 8-bit resolution consumes 1.7 µW, ENOB is 7.39 bits, and SNR equals 46.24 dB. The 4-bit resolution consumes 0.68 µW, ENOB is 3.58 bits, and SNR equals 23.45 dB. The total chip area is 0.18 mm2.
8-bit 22nW SAR ADC using output offset cancellation technique Karim M. Abozeid, Mohamed M. Aboudina, A.H. Khalil 2015 11th International Computer Engineering Conference Today Information Society What S Next Icenco 2015, 2016 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 Karim M. Abozeid, Mohamed M. Aboudina, A.H. Khalil ICET 2014 2nd International Conference on Engineering and Technology, 2015 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.
