摘要：

A Field Programmable Analog Array (FPAA), built in CMOS technology, contains uncommitted operational amplifiers, switches, and capacitors. An FPAA can be used to build filters for analog signals. The filter parameters are functions of the capacitor values. For an FPAA to be a viable substitute for dedicated devices we must examine the error performance of the implementation. Such performance analysis can be built into the software to provide circuit designers with additional information. A methodology is described for determining an error bound due to imperfections in the implementation of filter transfer functions.
