In this paper, we report the results of our theoretical studies on the phenomenon of self-imaging of periodic object under the illumination of zero-order Bessel beam. Our theoretical analysis indicates that the self-images are visible only after the walk-off distance of the Bessel beam used. It is also observed that the self-images bend around the optical axis of the setup. Besides, the present study...
In this paper, we have designed a β driven 1-bit full-adder circuit. Circuits based on threshold elements have raised extensive interest in recent years. It uses a CMOS(complementary metal oxide semiconductor field effect transistor) pair with variable β. Transformation of a regular analytic representation of the threshold function in a ratio form is the concept behind the design of the β driven circuit...
In this paper a new implementation technique of 1-bit full adder using Negative Differential Resistance (NDR) circuit composed of N-MOSFETs is presented. The design is based on Monostable to Bistable transition logic element (MOBILE) theory. In this circuit peak current level of the load and driver NDR is modulated by controlling the gate voltage of n-MOS device connected in parallel to the NDR element...
The DC analysis of a Metal Oxide Semiconductor Field Effect Transistor based negative differential resistor (NDR) is investigated. V-I characteristic of NDR is obtained by adjusting the parameters of NMOS transistors. Here the NDR circuit exhibits lambda type V-I characteristic. The circuit is easy to fabricate as all the components used here are NMOS. To study the characteristic curve of the NDR...
