A field-programmable analog array (FPAA) using switched-capacitor techniques

We present a voltage-mode switched-capacitor approach to the design of Field Programmable Analog Arrays (FPAA). The designed FPAA consists of uniform configurable analog blocks (CABs) which allow the implementation of different functions. The CABs are connected to each other via switched and unswitched capacitors. The internal structure of CABs and the interconnection network between them are configured by user-programmable digital control signals. The functionality of the FPAA is verified by embedding of different filters, programmable amplifiers, biquads, modulators and signal generators.
