Abstract :
A flexible and area efficient 2-D switched-capacitor FPAA architecture is proposed. In this architecture, a configurable analog block (CAB) can connect to 12 other nearby CABs and access to 10 programmable capacitor arrays (PCAs). The routing switches between CABs and PCAs are utilized for charge transfer required in switched-capacitor (SC) circuits. Therefore, it minimizes the number of connecting switches between CABs and PCAs, thereby, it reduces the settling time of the resultant SC circuits. Since this architecture has its unique connection properties, a specialized mapping algorithm for mapping SC circuit onto the architecture is also proposed in this paper
