AN10E40
Field Programmable Analog Array
The AN10E40 brings to analog what FPGAs brought to digital; extremely rapid production and prototype circuit
realization with field re-programmability. The AN10E40 consists of a 4 x 5 matrix of fully configurable switched
capacitor cells, enmeshed in a fabric of programmable interconnect resources. These programmable features are
directed by an on-chip SRAM configuration memory. The SRAM configuration memory is initialized on power up
via an off chip serial PROM or through the AN10E40Õs standard microprocessor peripheral interface.
A configuration memory image is easily constructed using the companion AnadigmDesigner¨ software which
includes an extensive library of adjustable, proven, pre-built functions. The configurable analog blocks are often
consumed one at a time, though some of the more complex library functions may consume two or more blocks.
Specialized IO cells surround the core to bring your analog signals in and out of the array.
The AN10E40 coupled with the intuitive AnadigmDesigner¨ software gives both digital and analog designers a
mcompetitive advantage in designing analog circuits that canÕt really be compared to any other design system in
existence. Quickly constructed, accurate, drift free, temperature compensated and programmable analog circuits
oare now yours. Imagine the power of programmable with the versatility of analog.

The Configurable Analog Block
The basic building block of the AN10E40 is the Configurable Analog Block. Each CAB is an op-amp surrounded by
capacitor banks, local routing resources, local switching and clocking resources, and global connection points. This
collection of hardware enables the CAB to perform many of the functions that could be achieved using an op-amp
and conventional passive components. All analog processing is accomplished with this switched capacitor circuit.
A Quick Review of Switched Capacitor Circuits
There are many excellent texts available which dive deeply into the details of sampled systems and MOS switch
capacitor circuit theory. The math gets very complex and may have kept you away from switched capacitor circuits
in the past. The good news is that the AnadigmDesigner¨ software for Anadigm¨ devices shields you from all the
complexities of using switched capacitor designs. Still though, it can be useful to review briefly how switched
capacitor circuits operate to eliminate the fear of the unknown.
Consider the following two circuits.

Figure 2. Switched Capacitor vs. Conventional Circuit
In the Figure 2, two circuits are shown that can both do the same job. The conventional circuit moves current
around the loop through the resistor. The amount of current of course is a function of the difference between V1
and V2 and the value of R.
The switched capacitor version of the circuit does the same job, but in a different way. With the switch in position 1,
charge moves from the V1 source to the capacitor C, when the switch is moved over to position 2, charge is then
moved from C to V2. As the switch is thrown back and forth, recognize that charge is moving over time, in other
words - current. The faster you throw the switch (and/or the bigger the capacitor is) the more current flows. Unlike
the conventional circuit, simply reprogramming the switching clock rate or the size of the capacitor allows you to
adjust the ÒresistanceÓ between nodes 1 and 2.
Of course, since this is a sampled system you have to keep in mind the frequency of the signal that is being
processed by the circuit and the frequency at which it is being sampled (or switched). For signals with frequency
content constrained significantly below the sampling frequency the switched capacitor circuit works just like the
conventional circuit. In all cases, the sampling rate should be at least twice as high as the highest frequency of the
signal being processed.
