Classification Transistor Amplifier

Image
A transistor amplifier must have a DC biasing circuit for several reasons. Especially, we will need two separate voltage supply to provide the desired class bias voltage to the emitter-collector and emitter-base. In fact it is actually only done in certain applications, but found that biasing voltage can be obtained separately from a single supply. Second, the transistor is very sensitive to temperature and creates a condition called thermal runaway. Thermal runaway will quickly destroy the bipolar transistor, because the collector current out of control quickly and will improve to the level of damage and the temperature will rise if there is no stabilizing the temperature at the amplifier to eliminate this effect. A common class for refractive surgery is a Class A, AB, B, and C. All of these classes use the same arrangement of the components to her on the operation of the DC bias transistor Q-point or different. Location of the variation bias point Q for different amplifie...

RF Amplifier with Op-Amp

Image
Op-Amp's right, not wrong title. I know the op amp is approximately 20 years ago, at age 741/301 series, an easy calculation (gain calculation), affordability, and simplicity of construction makes a very interesting op-amp. So many of the implementation of the op-amp, and even had time to try to build the "op-amp based computer". Almost all can be built with op-amp, except for RF. But that first, reversing the progress of semiconductor technology this condition, a few years back the manufacturers have managed to build an op-amp with a working frequency up to GHz. An article from Texas Instrument by Bruce Carter describes the application of op-amp (THS3202) on the rf circuit. 20dB RF gain op-amp Above circuit provides flat gain of 20dB in the range up to 200MHz.Terminasi input and output impedance is determined by the resistor 49.9Ohm. Strengthening the voltage is determined by resistor 301 Ohm / 5.16 Ohm. Choice of reinforcement could be done as to determi...

20W Surround audio amplifier with SI-1020G

Image
Have you been use the IC above? if those who have not, IC above is used or applied to the audio power amplifier. IC processing is quite good for use on amplifier home, or room. IC used is SI1020G who have not very high output with only 20W 8 ohm impedance speakers. Supply voltage ranging from 12 volt to 23 volts. Below schematic audio amplifier with IC SI1020G Part List R1 = 100K R2 = 1R C1 = 2u2F C2 = 100uF C3 = 47uF C4 = 10uF C5 = 2200uF C6 = 47uF C7 = 100uF 

Mini and simple power amplifier

Image
What is the meaning of the picture above? The above picture is a miniature audio amplifier and very simple. Here I will give an audio amplifier schematic is very simple which only requires a few components only, can be seen under this scheme. See from above scheme may occur to you, certainly cheap enough to make this amplifier and quite easy to make. The above simple audio amplifier circuit using an IC as the main amplifier and accompanied by other components. IC used is S1513, which requires a supply voltage ranging from 1.5 volts to 6 volts. And only 0.1 W output power with 4 ohm impedance. For a list components can be seen below. Part list C1 = 100nF C2 = 100uF C3 = 3n3F C4 = 1uF C5 = 1uF U1 = S1513

6 - 12 Volt audio amplifier

Image
The above is an amplifier circuit using supply voltages from 6 volts DC to 12 Volt DC. Power output of the amplifier is quite low with only 1 Watt 8 ohm impedance. You can apply this to the audio signal amplifiers that require strengthening are not so large as in the pocket radio. Part List : R1 =  100K R2 = 39R R3 = 100R C1 = 100nF C2 = 100uF C3 = 100uF C4 = 100uF C5 = 470uF C6 = 100nF C7 = 68pF C8 = 1nF C9 = 47uF IC = SFC2790C

50W car audio amplifier schematic

Car power amplifier uses SI1050GL IC as the main amplifier. The output power 50 Watt 8 ohm mono impedance. Up to 25 Volt DC voltage. with source voltage of this amplifier car battery has to work. Minimum of 12 Volt battery voltage, less than a sound or audio is issued less than the maximum and less good. You can assemble  this circuit amplifier with a schema like this. Part List R1 = 100K R2 = 1R C1 = 2.2uF C2 = 22uF C3 = 100uF C4 = 0.1uF C5 = 100uF U1 = SI1050GL If you want to make stereo amplifier , you must required multiply the two of components. 

450W Power amplifier

Image
Below it is a circuit of power amplifiers with power output of 450 watts mono , amplifiers are also frequently used in the amplifier a high-power amplifier, which used in an event, in the field and the placed closed. Because this amplifier suitable for the woofer, fullrange speaker, and can also be fixed for the subwoofer speaker.  To further strengthen and maximize the amplifier ,its power supply circuit also must be accurate, for electrolytic capacitors in power supply ,voltage capacitors use 80V or more, and a capcity 20000uF upwards, so when the bass amplifier is high , the voltage is not lot of experience dropping. Diode bridge use a minimum of 35A, or adjust the current input voltage. If the power supply has fulfilled the desire, the supply to the power amplifier.
