Side-channel attacks by cryptanalysis are becoming a serious threat for cryptographers, who are designing systems that are more robust in terms of hardware and algorithm threats, aiming to thwart violations of the secrecy of securely processed information. As our contribution on a related issue, we propose a new secure logic, called charge-sharing symmetric adiabatic logic (CSSAL), for resistan...

Abstract. The aim of the present paper is to analyse the influence of some input quantities on the fatigue resistance of a steel structure. The steel element subjected to many times repeated in-plane bending moment was analysed. The fatigue resistance was defined as the number of cycles causing the initial crack size propagation up to the critical size. The variability influence of input random...

Membrane potential and resistance were measured in eggs, cleavage stages and blastulae of the South African toad Xenopus laevis, using intracellular microelectrodes. The membrane potential increased from -6-5±2mV in eggs to -57±80mV at the mid-blastula stage. The input resistance of fertile eggs ranged from 0-5 MCI to 50 Mfi corresponding to a specific resistance of 20-200 k^cm. During the firs...

AbstructSmall-signal Thevenin and Norton equivalent circuits seen looking into each terminal of the BJT and the FET are described. The application of these! circuits to writing by inspection the expressions for gain, input resistance, and output resistance of multistage amplifiers is demonstrated. The application of the circuits to the noise analysis of devices is illustrated by the calculation...

In this paper, a CMOS implementation of a fully differential current-mode operational amplifier (COA) is presented. To achieve very low input resistance, a new technique based on a positive feedback is used in the input transimpedance stage. Additionally, traditional current output stage (Arbel Goldminz output stage) with improved output resistance is selected as a transconductance stage. Resul...

circuit offer some hindrance to the movement of electrons. Some conductive materials allow electrons to move more freely than others and are said to have low resistance. The unit of measurement for resistance is the ohm (Ω). Resistance can cause a problem at the interface between the electrode and the skin as the skin has high resistance and is also well supplied with sensory nerve endings. Thi...

Conventional delay circuits with one input cannot perform the task of generating delay between the input and output while operated at GHz frequencies. In addition, by switching 1 GHz signal at the input of conventional delay circuits, the signal suffers from distortion inside the chip. Whereas, the use of a resistance can control the delay and so becomes the cause of voltage loss inside the chi...

Junctional resistance between coupled receptor cells in Necturus taste buds was estimated by modeling the results from single patch pipette voltage clamp studies on lingual slices. The membrane capacitance and input resistance of coupled taste receptor cells were measured to monitor electrical coupling and the results compared with those calculated by a simple model of electrically coupled tast...

The passive electrical properties of subendocardial Purkinje fibers surviving in infarcted regions of canine ventricle 24 hours after coronary ligation were studied by using microelectrode techniques and cable theory. In normal hearts, cells within the subendocardial Purkinje fiber strands were found to be well coupled to each other but electrically isolated from neighboring myocardium. Voltage...
