Abstract
A field-programmable analog array (FPAA) fabric includes a 6×6 matrix of configurable analog blocks (CABs). The implementation of programmable CABs eliminates the use of fixed analog subcircuits. A unique routing strategy is developed within the CAB units that supports both differential and single-ended mode circuit configurations. The bandwidth limitation due to the routing switches of each individual CAB unit is compensated for through the use of a switch-less routing network between CABs. Algorithms and methodologies facilitate rapid implementation of analog circuits on the FPAA. The proposed FPAA fabric provides high operating speeds as compared to existing FPAA topologies, while providing greater configuration in the CAB units as compared to switch-less FPAA. The FPAA core includes 498 programming switches and 14 global switchless interconnects, while occupying an area of 0.1 mm2 in a 65 nm CMOS process.
