Classification Transistor Amplifier

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...

50Watt Audio Power Amplifier Circuit with LM3876

My account of architecture of this activity was to advance a bunched architecture for a stereo amplifier can be chip by a amiss (but the complete affection conscious!) Living apprentice at a university or a academy dormitory. The amplifier feeds a brace of speakers with two LM3876 amplifier chip circuits (50 watts per channel), or a brace of headphones Meier Crossfeed through...

60W inverter using transistors

Here is the circuit diagram of a fully transistorized inverter that can drive up to 60W loads. Transistors Q1 and Q2 forms a 50Hz astable multivibrator. The output from the collector of Q2 is connected to the input of the Darlington pair formed by Q3 and Q4.Similarly the output of Q1 is coupled to the input of the pair Q5 and Q6. The output from the Darlington pairs drive...

Circuit Serial To LCD

In making an electronic device using a microcontroller, we often faced with shortages in ports for line I / O or LCD viewer. In the article series LCD with 74HC595 Serial To this there is a solution to overcome the lack of ports or pins of the microcontroller is to convert the parallel bus system such as the LCD into a serial sequence To Serial LCD with 74HC595 this. The series...
