Abstract
A field-programmable analog array (FPAA) includes a digital signal routing network, an analog signal routing network, switch elements to interconnect the digital signal routing network with the analog signal routing network, and a configurable analog block (CAB) connected to the analog signal routing network and having a programmable resistor array. The switch elements are implemented via digital memristors, the programmable resistor array is implemented via analog memristors, and/or antifuses within one or more of the digital signal routing network and the analog signal routing network are implemented via digital memristors.
