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 ...

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 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. This basic VCO/waveform generator IC circuit includes a voltage follower loop (formed with IC1) and symmetry feedback loop (IC3) to eliminate an asymmetric duty cycle, which would cause ...

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 ...
