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 ...

许多电子应用需要根据其他信号的幅值来改变某个信号的频率。调频信号便是一个很好的例子，其中的载波频率随着调制源幅 ...

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 ...

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, ...

Last session, we use the cheap and cheerful 4046 Phase-locked Loop chip as a simple voltage-controlled oscillator (VCO). It was dead simple, in fact, because the chip has a VCO already built in. There ...

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 ...
