Due to their reliability, performance and rapid prototyping, programmable logic devices overcome the use of ASICs in the digital system design. However, the similar solution for analog signals was not so easy to find. But the evolutionary trend in Very Large Scale Integrated (VLSI) circuits technologies fuelled by fierce industrial competition to reduce Integrated Circuits (ICs) cost and time to market has led to design the Field-Programmable Analog Array (FPAA) which is the analog equivalent of the Field Programmable Gate Array (FPGA). In fact, the use of FPAAs reduces the complexity of analog design, decreases the time to market and allows products to be easily updated and improved outside the manufacturing environment.
