Pseudo-three-stage Miller op-amp with enhanced small-signal and large-signal performance
(IEEE, 2019)
Artículo / Artikulua,
A simple technique to implement highly power efficient class AB-AB Miller op-amps is presented in this paper. It uses a composite input stage with resistive local common mode feedback that provides class AB operation to ...
Subsampling OFDM-based ultrasonic data communication through metallic channels for monitoring of cargo containers
(IEEE, 2019)
Artículo / Artikulua,
An enhanced ultrasonic communication system based on piezoelectric transducers for monitoring of goods in cargo containers is presented. The proposed system consists of several sensors placed inside the container, whose ...
Low-power ultrasonic front-end for cargo container monitoring
(IEEE, 2019)
Artículo / Artikulua,
A low-power ultrasonic communication system conceived for cargo container monitoring is presented. Two piezoelectric transducers operating at 40 kHz are used for generating and acquiring an ultrasonic signal through the ...
