We present a novel circuit representation scheme, namely bond graph, along with strong-typed genetic programming for the evolution of analog filter circuits. Bond graph is a concise and uniform language for the description of circuit systems and more general engineering systems. Many unique characteristics of bond graph makes it an attractive candidate for representing circuit in genetic progra...

This work presents the implementation of multidimensional membership functions by means of an analogue Neuro-Fuzzy circuit realized in 0.8μm CMOS technology. The adopted circuit configuration is discussed and preliminary measurements of an integrated circuit prototype are reported. 1 Circuit implementation The fuzzy system model used in this work is based on the so-called fuzzy if-then rules [1...

In this paper, we study the computational complexity of commutative determinant polynomial computed by a class set-multilinear circuits which call regular circuits. Regular are with restriction on order in they can compute polynomials. A circuit be seen as analogue ordered defined Hrubes, Wigderson and Yehudayoff [5]. We show that if has small representation sum constantly many circuits, then p...

1 Introduction For analogue circuits the development of automatic test generation techniques is still a subject of In this paper we propose a fault-oriented technique for generating DC-tests for nonlinear analogue circuits. At the time being the circuits to be considered have single inputs and single outputs. An extension to circuits with multiple inputs and outputs is still under investigation...

A recurrent neural network is presented for solving systems of quadratic programming problems with equality constraints involving complex-valued coefficients. The proposed recurrent neural network is asymptotically stable and able to generate optimal solutions to quadratic programs with equality constraints. An opamp based analogue circuit realization of the recurrent neural network is describe...

Vertical n-p-n and lateral p-n-p transistor structures of an integrated circuit are studied using an electrolytic tank analogue and it is shown that the presence of a proper field plate extending from the collector-base junction over most of the base surface will improve the current-gain factor considerably. Experimental results of the analogue study, simulating typical carrier lifetimes and ty...

An analogue adaptive filter for dynamic response compensation of a load cell sensor is presented. The filter employs only transistors and therefore it can be integrated using standard digital CMOS technology, which is suitable for System-on-Chip applications. To perform adaptive compensation over a wide range of measurand, a novel CMOS multiplier circuit was developed. The analogue adaptive fil...

The development of macromodels of differential drivers for the prediction of the analogue operation of very high-speed digital communication links is explored. The macromodels are mathematical relations hiding the information on the internal structure of devices; they are estimated from port device responses and can be easily implemented in any circuit or analogue mixed-signal simulator as SPIC...
