Abstract :
This paper presents a Field Programmable Analogue Array (FPAA) based on switched-current (SI) signal processing technology. A design methodology for building complex switched current circuits using a four phase clock is proposed. A programmable building block; called the “Multi-function Block”, has been designed and can be used in a FPAA to implement circuits based on this four phase technique. The block was fabricated using 0.7 μm CMOS and test results are presented Simulation software for circuits built using these MFBs was written in C++. Example circuits, their implementation using MFBs and simulation results generated by this software are also presented
