提出了一种电压模式开关电容现场可编程模拟阵列（FPAA），可用于实现各种模拟电路。FPAA由统一的可配置模拟模块（CAB）组成，允许实现不同的功能。每个CAB由两个背靠背连接的反相和非反相杂散不敏感开关电容积分器组成。CAB之间的互连由开关和非开关电容网络实现。CAB的内部结构和不同CAB之间的互连由用户可编程的数字控制信号配置。FPAA的功能通过嵌入不同类型的滤波器、可编程放大器、双四极、调制器和信号发生器沿着仿真结果来演示。
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 non-inverting 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.
