If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, it’ll take a couple ...

LONDON — A series of functional 25-stage ring oscillators has been made by a team of researchers from the IBM T.J. Watson Research Center using silicon nanowire transistors with diameters down to ...

Unconventional AI Inc. has developed an artificial intelligence architecture that could improve the power efficiency of image ...

Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...

The growing demand for high-form-factor electronics has previously vitalized commercialization of flexible electronic devices, leading to extensive research on the design of deformable systems 1,2,3.

Can a simple medium-wave radio receive shortwave broadcasts? In 2005, Burkhard Kainka answered that question with a creative two-transistor converter.

Large-aperture electromagnetic phased arrays can provide directionally controlled radiation signals for use in applications such as communications, imaging and power delivery. However, their ...
