TITLE: RFID Reader Uses Field-Programmable Analog Array
Anadigm, Inc. has developed a single "universal" reader that can
be customized to read different radio frequency identification
(RFID) tag types, with different modulation schemes and
frequencies. The reader is a two-chip solution that uses a
customized Field Programmable Analog Array (FPAA) in conjunction
with an RFID State Machine. The FPAA provides configurable
analog opamps and interconnect. A single device contains a matrix
of twenty of these blocks and can perform common signal
conditioning functions for frequencies from DC to 500 KHz.
The part can be reconfigured in 100 microseconds. In some
situations, a single FPAA can replace a board containing several
discretecomponents and achieve higher accuracy and drift-free
performance over temperature. The dynamic reconfigurability of
the FPAA enables the device to adapt to changes in environmental
and operating conditions in near real-time. Furtheremore, the
FPAA can be used as a standardized platform that can support
multiple products and/or multiple analog sensors just by
programming the part for the desired application either at the
time of manufacture or even after installation. An extensive
development environment can be downloaded at no charge from
the web. It includes a design entry tool and floorplanner as
well as a simulator. Also included is a library of ready-to-use
circuits including summing amplifiers, integrators,
differentiators, comparators, band-pass filters, sine-wave
oscillators and full/half-wave rectifiers. A prototyping
circuit board is also available for purchase for $199.
