Abstract :
The paper describes a new CMOS current amplifier with prescribed input and output impedance. The circuit uses an inverse connection of a modified current conveyor. The calculation of input impedance, current gain and output impedance is given. The most demanding design parameter is the input impedance: it has an inductive component forcing this impedance to increase with frequency long before the current gain or output impedance deteriorates. The results of calculations are verified with simulations
