“…The voice, human expressions, and signs convey information to the external environment. Technically speaking, this information is baseband signals, or message signals that need to be transmitted to one or many receivers through a technique called modulation [7]. Linear modulation techniques like DSB, DSB-SC, SSB Modulation, and demodulation are prevalent in use.…”

<p>This study uses cutting-edge Field Programmable Analog Arrays (FPAA) technology to demonstrate the implemen- tation of linear modulations such as Double Sideband (DSB), Double Sideband with Suppressed Carrier (DSB-SC), and Single Sideband (SSB). The majority of the problems encountered when utilizing the DCS kit are avoided, thanks to the inclusion of FPAA. Double sideband modulation techniques for developing analog RF transmission systems have been used to create the FPAA circuits. The suggested solution enables reconstructing the analog conditioning step using an FPAA device, which may be tailored to the electrical characteristics and signal shape requirements. The multiplier is used to execute the DSB, DSB-SC Modulation, SSB Modulation, and Demodulation for a sinusoidal carrier signal. The structures’ functional components are created using the customizable analog modules (CAMs) of the FPAAs AN231E04 and AN220E04 from Anadigm designer2. The findings of the simulations and experiments are in good accord with the theoretical forecasts. An intriguing and promising proposal to implement the DSB, DSB-SC technology is disclosed and is based on the customizable analog blocks (CABs) architecture and Anadigm Designer2 software. The AN231E04 board, a creation of Anadigm Inc., is used to actually construct and verify the system.</p>

This paper proposes the use of field programmable analog arrays (FPAAs) as adaptive conditioning blocks for ultrasonic sensors. The uncertainty achievable through this technique, in fact, results very sensitive to the measurement conditions, due to the attenuation affecting the echo during its propagation. Indeed, FPAAs emulate analog circuits whose characteristics have to be dynamically tuned according to different operating conditions. Actually, the signal provided by the ultrasonic sensor is properly processed in order to improve the overall measurement accuracy.In this paper, the prototype of a distance meter based on timeof-flight (TOF) measurement is presented in order to evidence the advantages gained by FPAA features in processing the sensor output to compensate echo attenuation and distortion versus target distance.The prototype working is supervised by a digital signal controller (DSC) whose tasks are: 1) driving the ultrasonic transducer; 2) performing the echo acquisition; 3) tuning on the fly the FPAA features; 4) evaluating the TOF; 5) measuring the target distance; and 6) delivering the final result to the end user. This paper is completed by the results achieved in a number of experimental tests allowing interesting considerations to be drawn. In particular, the experiments confirm the prototype reliability and effectiveness also with ultrasonic echoes characterized by very low signal-to-noise ratios.Index Terms-Digital signal controller (DSC), distance sensor, field programmable analog array (FPAA), ultrasonic sensor conditioning, ultrasonics-based measurement uncertainty.

“…Unfortunately, FPGAs are suitable for digital circuits and cannot be used in analog and mixed systems. The solution in this matter are the FPAA systems, which are reprogrammable while processing analog signals and may be used to face the challenges for overwhelming high cost manufacturing of the mixed signal circuits [7][8][9][10][11][12][13][14][15][16].…”

Abstract.A rapid prototyping method for designing mixed signal systems has been presented in the paper. The method is based on implementation of the field programmable analog array (FPAA) to configure and reconfigure mixed signal systems. A serial algorithmic analog digital converter has been used as an example. Three converter architectures have been selected and implemented FPAA device. To verify and illustrate converters operation and prototyping capabilities, implemented converters have been excited by a sinusoidal signal. Analog sinusoidal excitations, digital responses and sinusoidal waveforms after reconstruction are presented.
