Amplitude modulation (AM) is widely used for not only wireless communications but also sensing and monitoring biomaterials as well as scientific data. Recently analog multipliers are attracting much ...

The two leading flat-panel display technologies—liquid crystal displays and organic light-emitting diode displays—have been compared. Liquid crystal displays (LCDs) currently have the upper ...

A concurrent dual-band voltage-controlled oscillator (VCO) with independently tunable dual oscillation frequencies is proposed. A shared square open-loop dual-mode resonator and two varactor diodes ...
