In the first two parts of this article, the first two generations of triangle-wave generator loops were presented – the foundational concepts at the heart of function generator (FG) technology. This ...

The first-generation integrator-hysteresis-switch FGs were replaced by a second-generation design scheme using current sources. The integrator-based FG loop can be improved by driving the integrating ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

If you have a modern function generator on your bench it is quite likely to contain a direct-digital synthesis circuit that creates arbitrary waveforms using a microprocessor controlled DAC. If you ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...

I take my hat off to engineers that know transistors in every intimate detail. The other day, searching for something else completely, I came across Nat Semi (now TI) document LB-38 ‘Wide range timer’ ...

It is difficult to get noise free signal in microwave frequency range of 30 gigahertz and above, Fujitsu has announced millimeter wave low noise signal generator circuit for automotive radar and other ...

Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as ...
