摘要：

An approach for designing a Field Programmable Analog Array (FPAA) is described. The analog array is based on current conveyors and benefits from two major interests: a large bandwidth and a low number of discrete components needed for the implementation of analog functions. An Analog Elementary Cell (AEC), based on current conveyors has been developed, and it is associated with programmable resistors and capacitors. Analog functions can be performed programming several AECs as current-mode amplifiers, analog multipliers, etc. The main purpose of this paper is to introduce current conveyor based analog blocks which are very-well suited for the implementation of FPAA. A particular interconnection architecture is addressed using current conveyors as switches. The major key feature of the proposed approach is that current conveyors are used as active elements and switching elements. A new topology based on the developed AEC is proposed and should be shortly validated.
