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… ...

“With Zoolark, debugging your circuit or scoping the waveforms of real electronics can be easy and fun, which means that you can study, build and play electronics ANYTIME and ANYWHERE you like.

The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

Our modification to the function-generator circuit allows low-voltage battery operation (Fig. 2). Current mirrors—Q1-R3, Q2-R4, Q3-R5, and Q4-R6—replace the resistors.

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.

A function generator is a handy piece of test equipment to have on-site. [Kammenos] designed and built his own function generator, using the bench itself as the enclosure.

The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical ...
