In this paper we present Matlab analysis as well as CMOS implementation of an analog current mode Kohonen neural network (KNN). The presented KNN has been realized using several building blocks proposed earlier by the authors, such as: binary tree winner t ...
Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
This paper presents the design flow from system-level specifications to transistor-level design for three different fully-differential amplifiers composing the first and the second integrator of a second-order hybrid multi-bit ΔΣ modulator. The circuit-lev ...
The design of distributed amplifiers in a CMOS process is investigated. In particular, the impact of parasitic elements from the transistors and from interstage inductors is studied. A methodology for determining an optimum design, including the number of ...
We present a complete top-down design of a low-power multi-channel clock recovery circuit based on gated current-controlled oscillators. The flow includes several tools and methods used to specify block constraints, to design and verify the topology down t ...
The domain of artificial neural networks has evolved rapidly during the last decade, and many research groups are presently working on new neuronal algorithms and investigating their potential for technological applications. The idea to use biologically in ...
A conception as well as a CMOS implementation of the analog, ultra low power and fully parallel image processor have been presented in this paper. Proposed circuit bases on the 2-D FIR filters realized using the Gilbert vector multiplier. Proposed filter e ...
We present a complete top-down design of a low-power multi-channel clock recovery circuit based on gated current-controlled oscillators. The flow includes several tools and methods used to specify block constraints, to design and verify the topology down t ...
Accurate modeling and efficient parameter extraction of a small signal equivalent circuit of MOS transistors for high-frequency operation are presented. The small-signal equivalent circuit is based on the quasi-static approximation which was found to be ad ...
The work introduces a mathematical framework and a corresponding implementable algorithm to automatically perform Volterra analysis of weakly nonlinear circuits. The analysis is based on the general composition rule for multivariate Volterra operators. The ...
