    An oft-overlooked parameter in semiconductor-based device structures is the presence of induced or spontaneous polarization. Polarization provides an added degree of freedom that can be used to fabricate new and innovative device structures both for electronics and photonics. We present a discussion of two approaches - the use of spontaneous polarization in GaN for nanoscale photonic devices and s... View full abstract»

    A multimodel scheme is designed for a tunnel-diode circuit. It improves the transient response in a transition or switching from a system equilibrium point to another one. Each model is obtained by a linearization of the circuit near an equilibrium point. Moreover, each of these models can be described as a combination of two transfer functions describing the plant behavior near two different nomi... View full abstract»

    Nowadays, the microelectronics market is characterized by an increasing complexity and integration, in particular in the field of application specific integrated circuits (ASICs) not only for digital but also for mixed-signal designs. The lack of a well defined methodology for analog synthesis, similar to the digital field means a serious drawback for analog and mixed signal design development. In... View full abstract»

    A profound study of a new digital AT (auto-tuning) technique for analog filters over very HF (high frequency) applications is reported in this paper. A 3% precision matching a 3rd-order LPF (low pass filter) characteristic frequency is shown using a 0.35 mum CMOS technology. The system consumes less area, power and tuning time than other proposed schemes. Post-layout simulation results show the bu... View full abstract»

    In this paper we propose to formulate the mean performance optimization of analog ICs as an expectation-based stochastic program, which can be further approximated as a more tractable optimization problem that interior-point methods can efficiently solve. Using such stochastic optimization approach, we can obtain statistical analog circuit designs with optimized mean performance. A ring oscillator... View full abstract»

    The content-based access of CAMs makes them of great interest in look-up based operations. However, the large amounts of parallel comparisons required cause an expensive cost in power dissipation. In this work we present a novel banked pre-computation based architecture for low-power and storage-demanding applications. Experimental results show that the proposed banked architecture reduces up to a... View full abstract»
