Software puts standard filters on analogue arrays
Anadigm has added filter synthesis to its field-programmable analogue array (FPAA) configuration software.
Typical applications for the AN120E04 will include signal conditioning, filtering, data acquisition, and closed-loop control in a wide range of industrial, automotive, medical, communications, automatic test equipment, and instrumentation systems, where the FPAA will be used to replace discrete components or analogue ASIC/ASSP devices.
In these applications, the AN120E04 provides a robust analogue implementation that avoids the temperature and process drift common to discrete solutions and the up-front costs associated with ASICs.
Built on a switched-capacitor architecture, the core of the AN120E04 is an array of identical configurable analogue blocks (CABs).

Software supprts reconfigurable analogue arrays
A breakthrough analogue EDA tool enables the design and implementation of dynamically reconfigurable analogue circuits within a matter of minutes.
A very flexible switching infrastructure surrounds the capacitor banks, enabling users to create complex configurations.
This allows the FPAA to implement an almost infinite range of analogue signal processing functions.
"The AN120E04 significantly enlarges the universe of FPAA applications by giving the market a programmable analogue device that greatly reduces cost-of-ownership for analogue signal conditioning applications, even in high-volume end products," said Michael Sera, Vice President of Marketing at Anadigm.
"Savings will come in the form of a faster design cycle, simplified purchasing and manufacturing, fewer service calls, and, in many cases, a lower bill-of-materials cost." The second-generation AN120E04 provides a 100dB narrowband signal-to-noise ratio as well as an extended bandwidth of DC to 2MHz, depending on the application.
A successive approximation register-based A/D convertor can be combined with an onboard look-up table to provide advanced analogue functions including sensor response linearisation, arbitrary waveform synthesis, signal-dependent functions, analogue multiplication, and signal companding.
Designers will program the AN120E04 using AnadigmDesigner2, a drag-and-drop EDA tool that enables the design and implementation of complex analogue circuits within a matter of minutes.
CAMs provided with AnadigmDesigner2 prepackage common analogue functions for which the user sets the parameters.
Simply by dragging and dropping CAMs, designers can create a complete analogue system on the FPAA, simulate it immediately, and then download it to the FPAA chip for testing and validation.
Once programmed by the designer, the AN120E04 can be reprogrammed and reconfigured repeatedly and indefinitely but the device needs to be powered down before reloading a new configuration bitstream.
For designs that can benefit from in-system dynamic reconfigurability, Anadigm offers the AN220E04 FPAA, which can be reconfigured on the fly without the need for power down.
Packaged in the 44-pin QFP, the AN120E04 device is sampling now, with production quantities scheduled to be available later this year.
Pricing in 10,000-piece quantities for US delivery starts at $7.95.
A multimedia demonstration of the new AnadigmDesigner2 EDA tool, designed for use with the AN120E04 and AN220E04, can be viewed at the Anadigm website.
A complete evaluation kit with a development board, entry-level software, and updated documentation is now available for $499.
