G enameled copper wire.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. As mentioned the biasing current should maximum of 5mA. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Always try to minimize the track length.

You can calculate the effective capacitance of the tuned LC circuit by determining the series capacitance of C2 and C3. This FM transmitter circuit performed well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation. Notify me of new posts by email.

The value of this resistor RB can be calculated using below formulae. Of the above types common emitter type is the popular and mostly used configuration. After that, the signals starts fading rapidly. This circuit uses only 10 parts including the coil.

I really need it. Submitted by webmaster on 23 November My prototype without the audio source connected, small enough to fit on a matchbox.

It can amplify power, voltage and current at different configurations. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. The coil is winded on a 3 mm drill bit, 16 turns of 0. As discussed a transistor will act as an Open switch during Forward Bias and as a closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.


When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Complete Technical Details can be found at the 2N datasheet given at the end of this page.

TL — Programmable Reference Voltage. Which is undesirable in this case. Fix the inductor with some wax for better frequency stability. As the transistor supports very high frequency range, you could expect significant amount of harmonics along with the main frequency. If both C2 and C3 are equal, the effective capacitance will be the half.

Please can You suggest simple as possible pll one. A Transistors acts as an Amplifier when operating in Active Region. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

To bias a transistor we have to supply datasgeet to base pin, this current IB should be limited to 5mA. Leave a Reply Cancel reply Your email address will not be published.
