The Commodore 64 may remain the best selling computer of all time, but it has one major flaw. It doesn’t have HDMI! That makes it a total pain to use with modern displays. Thankfully, [Side Projects ...

Abstract: A VCO-based RF modulator employing multiphase Pulse Width Modulation (PWM) is presented. The proposed RF modulator encodes the baseband signal into a set of multiphase PWM signals which are ...

Operating from 30 MHz to 1 GHz, the CMX993W wideband quadrature modulator provides translation from baseband I/Q signals to a modulated RF signal. Its wideband inputs (up to 100 MHz) can be driven ...

CMOS-based technology will allow low-cost integration of high-speed optical interfaces in silicon Addressing the problem of high-speed interchip interfaces, a technology developed by fabless ...

Abstract: A fast modulator for dynamic supply linear RF amplifier has been integrated in a 0.35/spl mu/m CMOS technology. The use of this modulator with an external linear power amplifier (PA) allows ...
