FPGAs are used in various applications like aero-space, automotive, military etc which require them to operate in different types of environments. Security of FPGA based system is a big concern as the system developed after lot of research can be stolen very easily. Nowadays, a lot of research is going on, considering various security aspects of FPGAs as the primary concern. Several cryptograph...

In recent years, thermal sensing in digital devices has become increasingly important. From a security perspective, new thermal based attacks have revealed vulnerabilities in digital devices. Traditional temperature sensors using analog-to-digital converters consume significant power and are not conducive to rapid development. As a result, there has been an escalating demand for low cost, low p...

Nowadays, due to the increasing complexity of circuits and systems incorporating mixedsignal components, many designers recognise the advantages of, and in some cases the necessity for, mixed-signal modelling and simulation of the circuits and systems as a whole prior to, during and post production of the circuit or system. This is particularly so within the microelectronics (semiconductor) are...

The synthesis of digital circuits is generally performed in two level logic switching algebra. But if we increase the representation domain from two level logic (N=2) to N>2 then the design of Multiple Valued Logic (MVL) digital circuits is possible. Interconnections play an important role in deep submicron designs as they affects power and area. Due to the requirement of interconnections the d...

For simple digital circuits, conventional method of designing circuits can easily be applied. But for complex digital circuits, the conventional method of designing circuits is not fruitfully applicable because it is time-consuming. On the contrary, Genetic Programming is used mostly for automatic program generation. The modern approach for designing Arithmetic circuits, commonly digital circui...

Since the rst reported oating-gate structure in 1967, oatinggate transistors have been used widely to store digital information for long periods in structures such as EPROMs and EEPROMs. Recently, oating-gate devices have found applications as analog memories, analog and digital circuit elements, and adaptive processing elements. Floating-gate devices have found commerical applications, e.g. IS...

The paper describes a digital circuit technique to process directly bit-stream signals from sigmadelta modulation based analogue-to-digital converters and the application of the technique to communication systems. The newly developed adder and multiplier are fundamental processing circuit modules. Using the fundamental modules and up/down counters, other circuit modules, such as oscillators, di...

The information revealed by derivatives can help to better characterize digital near-end crosstalk signatures with the ultimate goal of identifying the specific aggressor signal. Unfortunately, derivatives tend to be very sensitive to even low levels of noise. In this work we approximated the derivatives of both quiet and noisy digital signals using a wavelet-based technique. The results are pr...

A novel PDE solver using the multidimensional wave digital filtering (MDWDF) technique to achieve the solution of a 2D seismic wave system is presented. In essence, the continuous physical system served by a linear Kirchhoff circuit is transformed to an equivalent discrete dynamic system implemented by a MD wave digital filtering (MDWDF) circuit. This amounts to numerically approximating the di...

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...
