Abstract An accurate compact MOSFETs model that can deal with effects of temperature drift is prerequisite for analog circuit design. Although the mobility behavior at high vertical field region is important for simulating analog circuits, however current physics based models neglect the temperature dependence of that at this region. In this paper, a new mobility model at high vertical field re...

-This paper describes the realization of a fuzzy controller which implements the simplified inference mechanism. CMOS analog circuits where signals are represented as currents are employed. However, the whole system is externally communicated through voltages, thus enabling simple interface with conventional control circuitry.

The optics of axial silicon nanowire solar cells is investigated and compared to silicon thin-film solar cells with textured contact layers. The quantum efficiency and short circuit current density are calculated taking a device geometry into account, which can be fabricated by using standard semiconductor processing. The solar cells with textured absorber and textured contact layers provide a ...

Reducing absorber layer thickness below 500 nm in regular Cu(In,Ga)Se2 (CIGS) solar cells decreases cell efficiency considerably, as both short-circuit current and open-circuit voltage are reduced because of incomplete absorption and high Mo/CIGS rear interface recombination. In this work, an innovative rear cell design is developed to avoid both effects: a highly reflective rear surface passiv...

This paper develops a Genetic Algorithm (GA) based “growing” technique to design and synthesise analogue circuits with practical constraints such as the manufacturer’s preferred component values. Most existing problems with evolutionary search techniques applied to circuit design are addressed. The CA technique developed is then applied both to synthesise the topology of a network as well to pe...

Concurrent detection of failures in analog circuits is becoming increasingly more important as safety-critical systems become more widespread. A methodology for the automatic design of concurrent failure detection circuitry for linear analog systems is discussed in this paper. In contrast to previous approaches, the methodology aims at providing coverage in terms of all the circuit components w...

This paper describes a set of specialized GA methods for the analog circuit design, i.e., the component-list chromosome, the multi-staged evolution, and the size reducing pressure. In the several experiments, these methods have shown to achieve the robustness, the efficiency in time and the hardware consumption.

The second generation current conveyor CCII is introduced in this paper as a most versatile analog building block for realization of many other active circuits and applications. Short overview of interesting connections, using modular approach of design, with CCII are presented here, as well as two topologies of the conveyor, realized in CMOS technology, including their measured parameters.

This paper presents the design of an experimental electromechanical device for vibration control and energy harvesting. Traditionally, when the broadband resonant response due to a selected mode of a lightly damped structure needs to be controlled a vibration absorber is used. The resonance frequency of the absorber can be chosen to minimise the response of the structure under control. Optimisi...
