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 ...

The project was a signal generator that featured a swept RF output that could go from 1 MHz to 40 MHz. We had no way to make a single sweepable signal source that could cover a 40-to-1 range of ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...

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 ...

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 ...

The demand for analog and mixed-signal-based integrated circuits (ICs) has surged due to the increasing reliance on electronic-based applications across industries. As the world transitions to more ...
