On the basis of generalized theory of system design the behavior of the different design trajectories in the design phase space was analyzed. The problem of the initial point selection for the time-optimal algorithm construction was connected with the discovering of an additional acceleration effect of design process. This acceleration effect has been discovered by the analysis of various desig...

The task of a Broker is to interpret relevant knowledge acquired by cognitive and perceptual psychologists and bring it suitably to the notice of interaction designers, thereby avoiding the need for that designer to have knowledge of cognition and perception. The task is first illustrated by an example based on the concept of Design Actions and demonstrates the implication, for two different de...

The enhancement-mode MOSFET is the primary active device used in present-day digital and mixed-signal integrated circuit processes. Thus, it is important to introduce this device and associated circuit design methods early in the electronics curriculum. This article discusses four integrated circuit MOSFET amplifier configurations; the current source/active load stage, the source follower, the ...

Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

This paper describes a study of membrane potentiometers and long force sensing resistors as tools to enable greater interaction between performers and audiences. This is accomplished through the building of a new interface called the Helio. In preparation for the Helio's construction, a variety of brands of membrane potentiometers and long force sensing resistors were analyzed for their suitabi...
