Abstract: | The design details and test results of a field-programmable analog array (FPAA) prototype chip in 1.2-μm CMOS are presented. The analog array is based on subthreshold circuit techniques and consists of a collection of a homogeneous configurable analog blocks (CABs) and an interconnection network. Interconnections between CABs and the analog functions to be implemented in each block are defined by a set of configuration bits loaded serially into an onboard shift register by the user. Macromodels are developed for the analog functions in order to simulate various neural network applications on the field-programmable analog array |
