Reversible logic circuits are one of the solutions to the problem of conventional microelectronic technology reaching its limits. Unfortunately, efficient reversible system design requires different approaches than conventional solutions; the current methods of reversible function synthesis have certain limitations, including their complexity and scalability. This paper presents the application of functional decomposition, developed for conventional logic synthesis, as a potentially crucial step in synthesis of reversible logic. A decomposition of a Boolean function into a network of smaller sub-functions, subsequently synthesized into reversible blocks and composed into a reversible system, often yields better results than direct reversible synthesis of the original Boolean function. The experimental results presented in this paper demonstrate the potential of the proposed approach.

A low-voltage fully differential current-mode continuous time delta-sigma modulator is presented for application in electrochemical sensor arrays. Although a first order topology is realized by using a single differential integrator, second order noise shaping is achieved. A differential quantizer based on current controlled oscillators (CCOs) allows a current-mode implementation with high noise-immunity and low-voltage compatibility. Thanks to the differential design nonlinearity impact on circuit performance is kept low. Moreover, the typical clock-jitter sensitivity for continuous time modulators is addressed by a switched shaped-current feedback DAC. The modulator implemented in 180 nm standard CMOS technology consumes 28μW and achieves an SNDR of 95dB at a signal bandwidth of 10 kHz and an oversampling ratio of 256.

In this paper a comparison of four low noise amplifiers (LNAs), designed in fully depleted SOI 28 nm technology, has been presented. The objective of the presented work was to verify the usability of all kinds of MOSFET transistors that are available in UTBB for RF analog designs. The inductively degenerated cascodes were used in simulations. Such topology achieves high gain and low noise figure (NF). Simulated amplifiers were designed for a high sensitivity GNSS receiver, which operates in the Galileo/GPS E1/L1 band. The implemented circuits demonstrate the gain of 22.3 dB and the consumption current of 2.5 mA, with NF equal to 1.92 dB. For all amplifiers the supply voltage is 0.6 V and the silicon die estimated area is equal to 0.7 mm2.

The increasing demand for innovative systems, used for monitoring the biomedical parameters and comfortable for the patients, leads to the provision of better and better solutions. This paper presents the latest system design for the measurement of psychophysiological parameters for comprehensive use, developed at the Institute of Medical Technology and Equipment in Zabrze (ITAM), in light of previous ITAM projects and examples of global achievements in the field. The work weighs the benefits and downsides of the systems. The overview shows that the new system may become a competitive solution for the already existing options and that it is characterized by a number of properties that make it unique.

This paper presents the circuits and systems developed for testing the DSToTIC3 ASIC. Detailed study of the estimated noise performance in the presence of realistic external components is also a subject of this paper. DSToTIC3 is a prototype, 8-channel front-end electronics designed for the regime of long silicon strip sensors and interconnects of new tracking detectors. Layout and general architecture of the die is presented. Built-in digital-to-analog converters minimize the number of external components required for the chip operation, which makes it easily scalable to a final multichannel design.

This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a resonant cavity, which is useful in application with a very narrow spectrum of interest, such as bioluminescence imaging. Then, the authors discuss the application of those findings and the electrical advantages of SOI for a new kind of switching photodetector, the Hybrid MOS-PN device and their advantages in terms of dark current minimization.

Flexible capacitors were made using stainless steel yarns as yarn electrodes on textile substrate. The electrolyte material used was a dispersion of polyethylene dioxythiophene (PEDOT) : polystyrene sulphonate (PSS). After charging the capacitor for sufficient time, a sharp voltage drop was observed initially for a few seconds, then the voltage discharge slows down. It was not easy to establish the energy stored in the capacitor due to the self-discharge, however the capacitor could be used to power a TOSHIBA LC-810 calculator for 37. seconds.

Thermal characterization techniques require precise powering and accurate data acquisition equipment. The proper powering is complex due to electrical and thermal stability issues and some device properties. A few methods require trials to ensure the proper powering of the devices. New compound semiconductor devices have further stability issues at low currents and high voltages. This paper analyzes setups for powering two-pole and three-pole semiconductor devices with great emphasis on the stability issues. Methods are presented which ensure stability and proper powering on the devices, such as programmed powering technique, which eliminates oscillations as well.

The paper presents performance analysis of a permanent magnet synchronous motor (PMSM) drive with torque and speed control. The PMSM motor requires sinusoidal stator currents to produce constant torque. The paper presents constituents for the mathematical analysis of the motor operation within the dq-axis model. The mathematical model serves as inspiration for development of a drive design based on the DSP processor and IGBT power module. The measurement system consists of a control unit equipped with an inverter and an encoder, the PMSM drive (500W; 5Nm; 800 rpm), a torque measuring device and a motor that work in the generator mode. The performance analysis has been performed in two control intervals. It is possible to operate the PMSM with the speed that exceeds the rated rpm if the permanent-magnet excitation is weakened by a demagnetising field component produced by the stator winding. However, it leads to a decrease of the motor efficiency. The conducted experiments have shown, that in the second control interval it is possible to increase the motor speed by about 30% as compared to the nominal rpm (overspeed).
