This is a circuit of L200 light controller. The output of this circuit is controlled by the surrounding environment’s brightness. If the brightness increases, the output voltage will increases as well. Here is the circuit : The R1 and photoresistor are connected in parallel. They are used as regulator. If we connect the the photoresistor in parallel with R2, we […]

This is a schmitt trigger circuit. This circuit produces a simple comparator action. It is “emitter coupled”. This circuit has a distinct hysteresis loop and fast transition action because this circuit uses the 2N3565 bipolar that is a high hFE transistor. The 2N3069 JFET generates very little loading on the measured input. Here is the circuit : [Source: National Semiconductor […]

This is a circuit of precision current source. This circuit uses two kinds of transistor, the 2N2219 bipolar and the 2N3069 JFET. Both of them are used as voltage devices between the current sensing resistor and the output. As the current sensing resistor this circuit uses R1. Here is the circuit : This circuit is called current source because this […]
