In electronics the following trend is prevailing. Working voltages are becoming lower and lower and operating frequencies increase at the same time as downsizing is a key word when delay of electric signals between the active components has to be reduced. The discrete passive components are also becoming smaller and smaller and the component density on the interconnecting substrate increases.
This will cause an increase in production cost and failure risk at the same time as the probability of crosstalk grows due to unexpected parasitic capacitances and stray inductances. One step to solve these problems is the use of resistor networks. Next step is to integrate passive components in the printed circuit boards.
