The aim of this work is to assist designing of robust circuits to minimize the amount of defective circuits and therefore to increase the yield of production. The Fraunhofer ITWM considers electronic circuits at system level using its EDA software Analog Insydes, which allows analysis and symbolic approx ima tion of nominal analog circuits. The software now has been extended to handle parameter...

This paper presents electronic ballast with dimming capability supplying a 32 W fluorescent lamp. The electronic ballast is a self-oscillating driving circuit with an additional circuit responsible for dimming the fluorescent lamp based on a signal from a lighting dependent resistor. This luminous sensor measures the luminous flux level and set the lamp power by the voltage gain variation of th...

In the realisation of discrete-component analogue electronic circuits it is common practice, because of costs, to specify passive component values from a set preferred of values. For the design of Integrated Circuits it can also be desirable to use a standard set of passive component values. For example, to obtain accurate ratio matching of integrated resistors and capacitors by stacking identi...

There have been many influences and drivers for the development of technologies that allow functional components to be constructed at smaller and smaller scale. The semiconductor revolution in the second half of the 20 century was driven by cost, speed, novel function, and power consumption. Semiconductor science and its child, large-scale integration of electronic circuitry, have been responsi...
