IC 4049 Square wave oscillator generator

      We can bring the inverter CMOS digital IC is CD4049 Hex Inverting Buffer IC, to design the Square wave oscillator generator circuit diagram or Simple Pulse Generator circuits, to a lot circuit been simplified.

      The circuit we use a little equipment, just add a resistor and capacitor are the only one,It uses less energy. The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less.

      The pulse generators can also produce a 50% duty cycle square wave. The ICs in the circuit number CD4069,TC4069,LM4069.

      The frequency determined by R1 and C1 is F = 1 / (1.39xRxC). The power supply used DC 3V-12Volt.

    This site is facinating. Pls i will need a help in building my own inverter. I have the circuit but i need for efficient pulse generator with a variable resistor to control the trigger speed to the thyristor gate

    Could you please be specific re the frequencies – I need a variable range of 1.9 MHz to 2.35 MHz. Also – an amplitude of 9 volt. What would be the average current in such a case? Thanks.

    shall i use a suplly of 20v dc?? could please sugggest me to use 20v dc


    i need to build a square wave generator that has 3 pots in its schematic and uses a 741 op amp IC. if i say i don’t want to use the 741 is the any IC i can use and still achieve same results?
