Sometimes, the regulator does not work well so the regulator generate overvoltage that will destroy the system. To prevent system damage, a overvoltage protection circuit should be used. The overvoltage occurred when the regulator connects the raw DC supply to the 5V rail. This failure can be occurred due to the feedback loop opens up or the pass transistor shorts. […]

Sometimes the power goes down and we unable to save memory content. When the power goer down, the memory save circuit can be used to save memory content. This is a very useful circuit because the AC line dropout detection is not worthy. The difference of dropout voltage from two regulators is a basic of this circuit. This circuit uses […]

This is a Turbo Bass circuit. Using this circuit, the low frequency sound signals(bass) can be multiplied. This circuit is an active circuit. The first op-amp is used to buffer the audio input signal. The signal will be filtered by the second op-amp which will give bass signal output. Here is the schematic diagram of the circuit: The overall gain […]

This is circuit of NPN Common Collector Amplifier. This circuit can be used for impedance matching. This circuit similar to the Emitter Follower circuit because the emitter of this circuit is follows the base minus a diode drop. This circuit has voltage gain of one because the output voltage is forced to follow about 0.6V below the signal input. Here […]
