This article summarizes two experiments utilizing building blocks to find analog electronic circuits on a CMOS Field Programmable Transistor Array (FPTA). The FPTA features 256 programmable transistors whose channel geometry and routing can be configured to form a large variety of transistor level analog circuits. The transistor cells are either of type PMOS or NMOS and are arranged in a checke...

In this letter, a simple quadrature oscillator for built-in self-test (BIST) of integrated analog filters is proposed. A new hardware-efficient approach for amplitude control is described, with as main assets: (i) the technique requires little hardware which makes it very useful for BIST, (ii) the oscillation amplitude is well defined, and (iii) the distortion-level introduced by the amplitude ...

Field Programmable Mixed-Signal Arrays (FPAA) designs are reviewed and standard building blocks described with respect to circuit parameters and design limitations. The second-generation current conveyor is introduced as an analog building block with properties similar to those of an operational amplifier, and which has the potential for high frequency operation. A current conveyor can be imple...

This paper deals with the characterization of integrated circuits electromagnetic emissions. The TEM cell method is employed in order to identify primary emissions sources of complex digital devices. An 8-bit microcontroller, realized by a 0.8 m HCMOS process is considered. It is composed of several building blocks like the central processing unit, the analog to digital converter and the EPROM ...

We describe a CMOS neural net chip with a reconfigurable network architecture. It contains 32,768 binary, programmable connections arranged in 256 'building block' neurons. Several 'building blocks' can be connected to form long neurons with up to 1024 binary connections or to form neurons with analog connections. Singleor multi-layer networks can be implemented with this chip. We have integrat...

We report on a fundamental technological advance for multilayer polydimethylsiloxane (PDMS) microfluidics. Vertical passages (vias), connecting channels located in different layers, are fabricated monolithically, in parallel, by simple and easy means. The resulting 3D connectivity greatly expands the potential complexity of microfluidic architecture. We apply the vias to printing nested bioarra...

Standard tours combined with lack of information make many tourists miss some important experiences a destination has to offer. The target of the Dynamic Tour Guide (DTG) is to discover Tour Building Blocks (TBB), e.g. attractions like sights or restaurants, dependent on the actual context which is defined by personal interests, location and schedule of a tourist. It determines current informat...
