A field-programmable analog array using translinear elements

Abstract

A field programmable analog array that uses translinear elements for computation is introduced. The system uses floating-gate transistors to implement switch networks and MITEs to create reconfigurable translinear networks. The system architecture includes 3 MITE CABs, 1 specialized CAB for implementing four quadrant and dynamic functions, and a global switch matrix used to connect them. A squaring circuit, a square root circuit, a 2nd-order translinear loop, a vector magnitude circuit, and a 1st-order log-domain filter are programmed onto the device and results are presented in order to demonstrate the reconfigurability of the system.
