Abstract

A general configurable analog block (CAB) is presented, which consists of the programmable OTA, programmable capacitor and MOSFET switches. Using the CABs, the universal tunable and field programmable analog array (FPAA) can be constructed, which can realize many signal-processing functions, including filters. A prototype 5×8 CAB array has been fabricated. The chip has also been configured to realize a programmable OTA-C filter. From the simulated and measured results it has been found that filters with frequencies from several kHz to a few MHz can be realized based on the proposed CAB and FPAA
