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...

In order to handle noisy measurement data, an interval type-2 fuzzy logic system (T2FLS) is proposed. In this paper, the evolution of soft fault diagnosis for analog circuits is explored based on a type-2 fuzzy logic system (T2FLS) which can handle measurement uncertainties. In order to evaluate the values of the faulty components accurately, a type-2 fuzzy rule base is adopted to describe the ...

Analog and mixed-signal integrated circuits (IC’s) are rapidly becoming more complex. In addition to the traditional problems associated with testing IC’s, such as limited controllability and observability, analog and mixed-signal test is vulnerable to measurement induced errors. Constraints on measuring analog signals significantly increase the complexity and cost of testers for such circuits....

This paper describes a new reconfigurable analog array (RAA) architecture and integrated circuit (IC) used to map analog circuits that can adapt to extreme temperatures under programmable control. Algorithmdriven adaptation takes place on the RAA IC. The algorithms are implemented in a separate Field Programmable Gate Array (FPGA) IC, co-located with the RAA in the extreme temperature environme...

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...

With the advanced scaling of CMOS technology in the nanometer range, highly integrated mixed-signal systems can be designed. The use of nanometer CMOS, however, poses many challenges. This keynote presentation gives an overview of problems due to increased variability and reliability. Both have to be addressed by the designer, either at IC design time or through reconfiguration at IC run time. ...

A two-dimensional network for motion detection constructed with simple analog circuits was proposed and designed based on the lower animal vision. In the frog visual system, output signals which correspond to the two-dimensional motion direction and velocity are generated by performing simple information processing at the tectum and thalamus. The measured results of the test chip fabricated wit...

Abstract Analog ICs in general have many performance metrics that depends on multitude of device parameters. Parametric yield loss is often a problem in analog IC designs, where a significant portion of ICs manufactured fail specification test due to variation in process parameters. Parametric faults are mainly caused by statistical fluctuations in the manufacturing process. It causes the analo...
