Next, let’s look into the idea of using a digital logic to control the 555 pulse generator circuit frequencies. As we have learned before, the capacitor’s capacitance has a direct impact on the output frequency (F). So, based on this idea, we created the following simple four-selectable...
This Design Idea describes a delayed-pulse generator using a dual-CMOS D-type flip-flop (Figure 1). The circuit provides precision time delays of a trigger-input pulse. A dc-control voltage selects a time delay within the full-scale range. When the rising edge of a pulse triggers the ...
The generator was build using XR-2206 function generator IC, which is capable to generate sine, square, ramp and pulse waveforms in frequency range of 0.01Hz to 1MHz. The amplitude and frequency is modulated by voltage (potentiometers). The example circuit from datasheet worked well. Final ph...
As previously mentioned, the tester never will cause any sort of harm to the circuit under check; alternatively, it is best to include diodes D1 and D2 in order that the circuit under test is no way able to counter damage the tester parts. So long as you don't have an electrical int...
Simple Electric Light Circuit An electrical circuit consists of an electrical device to provide electrical energy to the charged particles like a battery otherwise a generator; current-carrying devices such as motors, computers, lamps, connecting wires, etc. The performance of electric circuits can be...

The operating frequency of this astable is determined by the values of C1 and R11. This circuit configuration works well as a clock-pulse generator for feeding the IC1's 74C164 shift register. The positive output pulses from the clock at pin 4 of IC2 are supplied into the shift register...
Here is the schematic circuit for the controller: As you see, i only use the 4017 CMOS chip. This is a decade counter/divider. The input pulses comes from your pulse generator. Each pulse, will increase one count to the 4017. This will happen 4 times, for counts 0 to 3. When in ...
A pulse width of around 150µsec is sufficient to see the full voltage sag and recovery in most DC/DC converters, so the PWM frequency can be set at around 330Hz. It is most convenient to power the circuit via a Li-Ion battery; this makes the circuit fully isolated and avoids ...
The LM22680 stability can be verified using the WEBENCH Designer online circuit simulation tool. A quick start spreadsheet can also be downloaded from the online product folder. The complete transfer function for the regulator loop is found by combining the compensation and power stage transfer ...
