Posted June 24, 2018 Why do you show text that talks about an NPN transistor but you show a schematic with a PNP transistor? The Circuitspedia PNP circuit is missing the important diode parallel with the relay coil. The diode is shown on their NPN circuit. Quote Join...
The fundamental op amp circuit (Fig. 13 above) employs an NPN transistor and an op-amp to generate an output proportional to the input's log: VOUT = (- k log10) VIN/RIo The "inverted" circuit, working as a fundamental anti-log amplifier, is depicted in the lower diagram. Typically,...
A very common circuit to build as a beginner is theblinking light circuit. Transistor Find the transistor symbol in theschematic symbols overview. This is probably the hardest of the basic electronic components to understand. But don’t worry, it’s not that hard. ...
A simple BJT common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies. It is used as a voltage amplifier. In this circuit the base terminal of the transistor is the input, the collector is the output, and the emitter is common to ...
The function of both the PN junctions is controlled by providing bias to the circuit through some dc supply. The figure below shows how a transistor is biased.By having a look at the above figure, it is understood thatThe N-type material is provided negative supply and P-type material is...
Transistor Current Mirror charge pump diode for forward drop bias voltage diode logical or H Bridge An H bridge is an electronic circuit that causes current to flow in one direction or the other ( from a single ended power supply ). Often used for motor control motor driver. It is an elec...
