This paper devotes to a new 7-2 compressor designed according to a new architecture with a pure Glitchless output. A considerable increase in the speed of the operation is achieved by utilizing a new truth table, fast production of signals Cout1 and Cout2, optimum tuning of the width of the utilizing transistors, and eliminating the parasitic capacitances through merging the drain of transistors. Additionally, the number of transistors used in this architecture (74) is less than the recent 7-2 compressors. The proposed structure's delay proved by the results of the simulations applied to Hspice software using standard TSMC 0.18μm CMOS technology is about 285ps.

This paper discusses on the practical example of a power diode attached to a heat sink the problem of heat transfer coefficient temperature dependence and its importance for free convection cooled electronic systems. The average values of this coefficient are estimated from multiple measurements of device cooling curves performed for different device heating currents. These values are used then for transient simulations of the device with compact thermal models.

The paper presents the idea behind the implementation of the BioSiP system designed for monitoring biomedical parameters and the patient's behaviour, based on the architecture of a measurement module system located on the subject's body. The system could be developed owing to the market launch of new generations of electronic devices combining high functionality, small size and low power consumption. The paper presents the elements being part of the BioSip system, as well as hardware solutions selected for the assumed objectives, i.e. ensuring communication between system elements that would be efficient and resistant to artefacts, extending the time of operation for battery power supply, as well as ensuring a satisfactory reliability level and comfort of use.

A stable reference voltage (or current) source is a standard component of today's microelectronics systems. In particle physics experiments such reference is needed in spite of harsh ionizing radiation conditions, i.e. doses exceeding 100 Mrads and fluences above 1e15 n/cm2. After such radiation load a bandgap reference using standard p-n junction of bipolar transistor does not work properly. Instead of using standard p-n junctions, two enclosed layout transistor (ELTMOS) structures are used to create radiation-hard diodes: the ELT bulk diode and the diode obtained using the ELTMOS as dynamic threshold transistor (DTMOS). In this paper we have described several sub-1V references based on ELTMOS bulk diode and DTMOS based diode, using CMOS 130 nm process. Voltage references the structures with additional PTAT (Proportional To Absolute Temperature) output for temperature measurements were also designed. We present and compare post-layout simulations of the developed bandgap references and temperature sensors, which show correct operation (<;1mV bandgap stability, linear PTAT) in teperature range -20 to 100 celsius degree.

A 900MHz frequency synthesizer is presented in this article. The purpose of the proposed architecture is to minimize lock time in Phase-Locked Loops (PLLs). The structure has been simulated by HSPICE software in a typical 0.18um CMOS technology at the supply voltage of 1.8V. Simulation results prove that the designed frequency divider locks instantly that is a lower lock time compared to conventional PLLs.

In this paper a new voltage reference circuit concept is introduced. The presented voltage reference circuit is especially useful for low power applications. The reference circuit has two modes: the high accuracy and the low power mode. During the high accuracy mode the energy consumption is much higher than during the low power mode where accuracy is secondary. The fields of application are use cases where different specifications are required at different points in time. As an example a lot of chips in mobile devices switch between operational and sleep modes. During operational mode high accuracy is needed. Afterwards, when the chip is in sleep mode for a long time, the current consumption has to be at a minimum.

We report on design of the 100 channel integrated circuit (10×10 pixel matrix) destined to complex neurobiology experiments. The chip is dedicated to both recording and stimulating neural activity and its predominant attributes comes from its individual digital control of both blocks and allocation of both in each of the pixel. Additionally, the integrated circuit is composed of RAM, ADC, bandgap reference, programmable analog multiplexer and programmable biasing block. The chip is designed in CMOS 180mn process and occupies 5×5 mm2. The paper focuses on design of these type of chips in order to facilitate its tests. The main IC's blocks are described and its preliminary measurements are shown.

This paper deals with design of readout system, and then its monolithic implementation, intended for spectroscopy in THz range. At the beginning, the fundamentals of THz spectroscopy based on selective NMOS pixel line, and its possible applications for materials identification are presented. Next, the preceding work on single-channel readout circuit is shortly recalled, with a special emphasis on the last design version featuring selective chopper amplifier. This IC became the basis of the complete readout system addressed in next few sections of this paper. Finally, design of novel integrated circuit is presented, incorporating the multi-channel readout circuit dedicated for pixel line.
