The output frequency of the simple VCO in Figure 1, which is synthesized from inverting latch stages, is tunable to an integer multiple of the input frequency by selecting which output phases feed ...
Often, there is a need to simulate RFIC designs with substrate parasitics to accurately represent high frequency effects in actual silicon. Generally, parasitics appear from a chip's surface layers, ...
HSINCHU, Taiwan--Feb. 21, 2006--UMC (NYSE:UMC)(TSE:2303), a world leading semiconductor foundry, today announced that it has fabricated a push-push Voltage-Controlled Oscillator (VCO) with an ...
Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...
Sponsored by: Texas Instruments. A phase-locked loop, of course. A PLL frequency synthesizer plays a key role in delivering the precision and accuracy demanded by many applications. The master timing ...
Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...
