The CMOS current controlled oscillator circuits (CCO)

Schematic Diagrams      Comments Off on The CMOS current controlled oscillator circuits (CCO)

We can use a CMOS nand gate or inverter gate and two transistors into the current controlled oscillator circuit (CCO). In Figure 1 use two inverters are connected together as a astable multivibrator circuit. Figure 1 the normal astable multivibrator CCO circuit. If the output of N1 is “0”, and… Read more »

Simple transistor tester circuits

      This is the Transistor tester into the Circuit or PCB. When your project do not works, the tester electronic parts or component be what need very much. Only by measuring transistor I’m tired of having to remove out one by one measuring. It wastes time and makes damage to the… Read more »

Simple Electronic clock sound using IC4011

The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can… Read more »
