3、 people, but how to use the electric current conveyer is still a complex problem. The filter using the electric current conveyer is more stranger. But electric current transmission characteristic of the electric current conveyer has caused it to be the most basic product log in the electric current
4、pattern VLSI electric circuit. Electric current conveyer characteristic and the realization is explained in this article, The article has induced take the electric current conveyer as the active device active network part simulation inductance electric circuit, and has carried on the analysis to the simulation inductance. Then the principle and design method of LC trapezoid high-pass filter is introduced. After that the LC trapezoid high-pass filters inductance is replaced wi
