The FET untuned oscillator circuit consumes roughly 2 mA from the 6-volt DC source. With this source voltage, the open-circuit RF Output voltage is around 4% volts rms DC supply voltages as much as 12 volts could be applied, with correspondingly increased RF output. To find out if theosc...
An oscillation circuit with a free starting circuit (ALS), when the discharge lamp (EL) to provide low-pressure gas supply, which is particularly suitable for the power supply means ((EVG)) of the field effect transistor half bridge. 通过使用起动电容(C5),可以放弃采用双向开关二极管. By using...
In this article I have explained how to make a very simple circuit for buzzer using piezo electric transducer, two resistors, a small coil and a BC547 transistor. A buzzer is a high frequency oscillator circuit used for generating a buzzing sound through a transducer or speaker output. Content...
For a microstrip mounted Gunn oscillator, a simple equivalent circuit can be found phenomenologically, allowing for non-linearity, from the measurement of oscillation frequency and output power as functions of a circuit parameter. Based on this equivalent circuit, optimum circuit design is possible, e...

Circuit Connection In this system, a 555 timer is used as an oscillator that is capable of generating pulses at a maximum of 10 minutes time interval. The frequency of this time interval can be adjusted by using the variable resistor connected between the discharge pin 7 and the Vcc pin 8...
Everyone is a newbie when they first start. In electronics, one of the best and satisfying things to create is an FM transmitter. This is maybe just me but it is still fun to create an FM transmitter even for a pro. So here is a very simple circuit to create an FM transmitter. ...

To keep things simple, I show only a two phase circuit, but more phases are possible by adding more resistors or pots (a classic three-phase oscillator could be created fromFigure 2if R3 was split into equal halves and the signal from this midpoint was inverted relative to the other two...
14) LOW FREQUENCY AUDIO OSCILLATOR The circuit uses two NAND gates connected as inverters and cross coupled to form an astable multivibrator. The frequency can be altered by increasing the value of CI and C2 (lower frequency) or decreasing the value of C1 and C2 (higher frequency). Aselectrol...
