The circuit is a simple transimpedance amplifier that converts the device under test’s (DUT’s) IDS into an output voltage (Fig. 1). O p-amp U1A maintains the DUT’s source voltage at 0 V.

The output frequency can be set precisely and it can also be used as a sweep generator to test the frequency response of audio circuits, and more. I’d like to talk some more about the real build of a ...

Meanwhile, Deavenport needed a slow ramp circuit to test the DVM he was developing. So he designed a simple function generator using circuitry that had been around a long time. Deavenport's circuit ...

12:43 pm September 5, 2018 By Julian Horsey Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own.

This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals with three different simultaneous outputs at the same frequency ...
