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 ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina ...

Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

This circuit, a modification of a function-generator circuit, comprises a battery-powered sinewave generator that is continuously adjustable from 100 Hz to 10 kHz. We needed a handheld, ...

Eve in Motion has created a new pocket sized mini oscilloscope and function generator which they have launched via Kickstarter this month to raise the required funds needed to take the design from ...

The 1510A Precision Signal Source generator available from MTI Instruments is a compact and portable device and includes dual-channel Direct Digital Synthesis (DDS) that creates high precision signals ...

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’ ...
