“…Combinations of sound localization techniques are also possible when targeting distributed networks. The authors in [81][82][83] propose a distributed network of FPGA-based microphone array nodes for sound source localization and separation. The architecture includes a voice activity detector (VAD), the MUSIC algorithm for the sound-source location and the Delay-and-Sum beamforming technique for the sound sources separations at the network level.…”

Over the past decades, many systems composed of arrays of microphones have been developed to satisfy the quality demanded by acoustic applications. Such microphone arrays are sound acquisition systems composed of multiple microphones used to sample the sound field with spatial diversity. The relatively recent adoption of Field-Programmable Gate Arrays (FPGAs) to manage the audio data samples and to perform the signal processing operations such as filtering or beamforming has lead to customizable architectures able to satisfy the most demanding computational, power or performance acoustic applications. The presented work provides an overview of the current FPGA-based architectures and how FPGAs are exploited for different acoustic applications. Current trends on the use of this technology, pending challenges and open research opportunities on the use of FPGAs for acoustic applications using microphone arrays are presented and discussed.

“…Various techniques have been developed to realize ubiquitous computing for sensors. With implementation of more sensors, more analog-to-digital converters (ADCs) are required by the many sensors to digitize the many channel signals [1], [2]. To date, the ADCs on an LSI chip have been limited numerically by the chip area.…”

We present an I/O-size second-order analog to digital converter (ADC) combined with a time-to-digital converter (TDC) and a voltage-to-time converter (VTC). Our proposed VTC is optimized for metal-oxide-metal (MOM) capacitances, and is charged to the MOM capacitances by an input voltage. In a standard 65-nm CMOS process, a signal to noise and distortion ratio (SNDR) of 50 dB (8 bits) is achievable at an input signal frequency of 78 kHz and a sampling rate of 20 MHz, where the respective area and power are 6468 mm 2 and 509 µW. The measured maximum integral nonlinearity (INL) of the proposed ADC is −1.41 LSBs. The active area of the proposed ADC is smaller than an I/O buffer. The proposed ADC is useful as an ADC I/O.
