  • 10 MHz oscillator

    This circuit can oscillate up to 10 MHz at VDD 3-15V. You can determine the output frequency by chaging VDD(see table). <cut> In this example I use 4070 CMOS. VDD(V) Frequency(MHz) Amplitude(V) 5 2.4 3.5 10 9.4 8.0 15 11.0 12.0 </cut> VN:F [1.6.9_936]please wait…Rating: 9.0/10 (1 vote cast)VN:F [1.6.9_936]Rating: 0 (from 0 votes)

  • Sawtooth wave generator

    Sawtooth wave generators using opamp are very common. But the disadvantage is that it requires a bipolar power supply. VN:F [1.6.9_936]please wait…Rating: 5.5/10 (2 votes cast)VN:F [1.6.9_936]Rating: 0 (from 0 votes)

  • Simple variable frequency oscillator

    This is a very simple circuit utilising a 555 timer IC to generate square wave of frequency that can be adjusted by a potentiometer. VN:F [1.6.9_936]please wait…Rating: 0.0/10 (0 votes cast)VN:F [1.6.9_936]Rating: 0 (from 0 votes)
