Thanks for the fair opinion. I will redraw the two voltage diagrams illustrating only the input part with the three resistors. It is also possible to split the article into two parts - in the first, to remain only building the circuit in six steps (the structure evolution), and in the second, to cons... (more) |

What is the idea behind the op-amp instrumentation amplifier? Building the circuit structure The classic circuit of the op-amp instrumentation amplifier is an example of an ingenious circuit solution. The best way to show it is by reinventing the circuit step by step. Here is my "building scenario"... Step 1: Single-ended amplifier Let's assume the... (more) |

Why does the collector current depend linearly on the base current? It is well known that there is a linear relationship between the BJT collector and base current (Ic = beta x Ib). It would be interesting to explain it in an intuitive way. The power of such a "philosophical" approach is that it can explain various specific implementations. The idea In the BJ... (more) |

How does a transistor maintain a constant current? In contrast to diodes that maintain a relatively constant voltage when the current through them varies, a fundamental property of all types of transistors (BJT, FET...) is to maintain a relatively constant current when the voltage across them varies. How do they do that? As in the case of diodes, ... (more) |

| Comment | Post #284995 |
I agree with your arguments. I used the resistance because it is the most primary quantity that leads to a change in the other quantities (current and voltage).
I think in such a way: The diode is a passive element that does not produce or accumulate energy. So, the only thing it can do, is to ch... (more) |

How does a diode maintain a constant voltage? A fundamental property of all types of diodes (silicon, germanium, Schottky, LEDs, Zener ...) is to maintain a relatively constant voltage when the current through them varies. How do they do that? This question can be answered specifically by considering the processes in the semiconductor PN junc... (more) |

What are voltages inside resistors? Need to visualize voltage distribution Once visualized the voltages of the internal circuit points, we can go even further and "enter" inside resistors to visualize the voltages along the resistive film. This will allow us to see some interesting points (for example, virtual ground), the operati... (more) |
