## Abstract New CMOS current differential amplifiers are proposed suitable for analogue signal processing at high frequencies. They consist of simple current mirrors, which are easy to design and to implement in IC form. Lowβvoltage lowβpower design is feasible. Relying on these devices a number of
In radio=radar observations of natural targets, such as planets, satellites, asteroids and comets, the Earth's surface or the ionosphere, the troposphere and the stratosphere the response of the target to a signal can often be thought of as the response of a time-varying circuit. In recent investiga
## Abstract In this article, we have obtained simple excess capacitance formula for asymmetric stripline openβend. The average error of the formula is less than 2%. On the basis of this formula and the fieldβbased equivalent circuit model obtained by the authors before, a lowβpass filter and an edg
