摘要：
We present a voltage mode switched-capacitor Field Programmable Analog Array (FPAA) to be used to implement various analog circuits. The FPAA consists of uniform configurable analog blocks (CABs) allowing implementation of different functions. Each CAB consists of two back-to-back connected inverting and noninverting strays-insensitive switched-capacitor integrators. The interconnection between CABs is implemented by switched and unswitched capacitor networks. The internal structure of CABs and the interconnection between different CABs are configured by user-programmable digital control signals. The functionality of the FPAA is demonstrated through embedding of different types of filters, programmable amplifiers, biquads, modulators and signal generators along with simulation results.
