In some applications it is necessary to transmit square waves across a long cable. However, long cables typically have high capacitance, which can significantly affect the signal’s wave shape. As such ...

The circuit here is an oscillator with an unusual frequency divider that I designed when I was developing an RF system. I needed a stable and accurate 455kHz digital signal generator that used as few ...

A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...

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 ...
