Fig 3. The pulse-generation circuit uses two 555 timing circuits to create a square wave with a duty cycle controlled by variable resistor R28.

The circuit diagram is shown in the code. The 555 timer has three main terminals: trigger, threshold, and discharge.

The monostable multivibrator circuit using the 555 Timer IC was successfully designed and simulated to generate a single output pulse of 0.5 microseconds in response to a trigger signal. The output ...

Note that all of the 555 devices that I tested worked OK, including the CMOS TLC555. To test this feature, I constructed a simple test circuit and took oscillographs of the signals. Pin 7 output ...

A 555 set up in astable mode running at 31.25 Hz provides the clock, synchronized with the signal by connecting the comparator’s output to the 555 trigger input.

This causes the circuit to power on whatever is connected to it. When the sun rises, the resistance on the reset pin drops and the 555 timer continually resets until it gets dark again.

A close look at the circuit reveals that it consists of a discrete D-type flip-flop formed by NAND gates U1a-U1c. The setup delay of the LS series gates is around 10 ns. This causes the settling ...

A tunnel diode switching circuit is discussed which is useful as well as representative and yet is simple and amenable to detailed analysis. A stability diagram is given showing how the equilibrium ...
