RS flip-flop, or reset-set flip flop, is a kind of stable multivibrator with two input, namely reset and set. The output will be at one of two stable states, set (active) or unset (inactive). A pulse strobe on set input will activate the output, and a strobe on reset input will deactivate the output. This two stable stage are provided […]

With the help of high gain high impedance operational amplifier, we can build a long time delay with resistor-capacitor (RC) circuit since it allow high resistance resistors to be used. We can calculate the time (t) using the following formula; Time (t) = R4.C.ln(Vr/(Vr-Vi)). For design example is a 100 second timer, where this circuit uses this following components: Vr=10V, […]

The circuit below is a one-shot multivibrator. One shot multivibrator is also known as monostable multivibrator, or timer. The main function of such circuit is producing a fixed width pulse. The width of this pulse is determined by the component value selection at the time of designing the circuit. The main component of this circuit is the LM139, and this […]

One shot multivibrator circuit is also known as monostable multivibrator or timer. The function of such circuit is simply produce a pulse strobe with a fixed width, regardless of the pulse width of the triggering input. Below is the circuit’s schematic diagram of simple one shot multivibrator uses one section of an LM139 comparator. The width of the output pulse […]
