This Sawtooth wave generator circuit include of the frequency oscillator is controlled by current. Which can generate the sweep frequency in wide range. Suitable to be applied in the field of music equipment and a narrow pulse output. Also we are able to be a random circuit, and Hold. This circuit include of current variable […]

We can easily use FET and Crystal to generate the frequency and In particular, this circuit use very low voltage. It can operate at a supply voltage to 1.5 volts only and at crystal frequency 100 KHz to 10 MHz. The crystal is connected to between the drain and gate of FET-T1 BF256. It runs […]
This is simple crystal oscillators that provided square wave of 1MHz to 10MHz, Use an inverter gate IC and control frequencies with crystal. A oscillator or a frequency generator provide waveform out in various forms. For example : sine wave, Triangular waveform, Or square wave. The Frequency generator to control or out for a base […]
Mr jafar need to use the 12 volts 1 amp DC Power Supplies. In my sites has many circuits related them. – Cheap and old but sure, use transistor and zener as main http://www.eleccircuit.com/simple-regulator-by-transistor-c1061/ http://www.eleccircuit.com/dc-power-supply-9-volt-using-tip31-transistor/ – Cheap and popular all times, use IC7812 http://www.eleccircuit.com/regulator-5v6v9v12v-1a-by-ic-7805780678097812/ Note: If you have a 1A normally circuit. So your 12V […]
