Then to summarise, this type of bipolar transistor configuration has a greater input impedance, current and power gain than that of the common base configuration but its voltage gain is much lower. The common emitter configuration is an inverting amplifier circuit resulting in the output signal being 180o out-of-phase with the input voltage signal.

Diodes in Parallel Configuration ... That current source will simply make 10000 Amps flow if that is what it takes to make 9 V. Then 9999.998 Amps will flow through the diode and 2 mA will flow through your 5 k meter. What you need to do is add some resistance in series with the voltage source. Start with 100 ohms and see how that goes. The voltage drop introduced by each diode varies by the Zenier value. The circuit above uses one 3.6V and two 3.3V zener diodes. Zener diodes with higher breakdown voltages have larger voltage drops when conducting in reverse. The ATtiny85 works over a wide voltage range (1.8V - 6V) so a regulated voltage source is not needed. This is a problem with its solution: What I don't understand is how he replaced the three diodes with the voltage sources in DC-analysis or with the resistances in AC-analysis. What assumptions did he make to do that?. For DC-analysis: if it was one diode then it's ok for me but the problem is with the three connected in series.

However upon looking the answers, it says that the current across the diode is 0A. This means that the diode is actually "off" (while the other diode is on), and thus my analysis is wrong. Is there a problem with my reasoning or am i missing something crucial? Welcome to electronics, this is Dr Ferri. This is a problem on diodes, and I'm going to show you how to analyze these diodes. I would like to be able to use engineering intuition to be able to tell what state we're in, because I've got two diodes, they can both be conducting or not conducting, in other words on or off and I want to tell which they are.

You are free to choose your own configuration. * A diode may be thought of as an electrical counterpart of a directional valve (\check valve"). * A check valve presents a small resistance if the pressure p >0, but blocks the ow (i.e., presents a large resistance) if p <0. * Similarly, a diode presents a small resistance in the forward direction and a large resistance in the reverse direction. Series Diode Configuration •It’s assumed that the forward resistance of the diode is usually so small compared to the other series elements of the network that it can be ignored. • In general, a diode is in the “on” state if the current established by the applied sources is such that its direction matches that of the The voltage Vo depends on the type of Si and Ge diodes. Using the "standard" forward voltage drop of a Ge = 0.2 volts and a Si = 0.7 volts the Ge dominates and Vo = 11.8 volts. But with real parts it's different. Take the case of the ubiquitous 1N34 Ge diode; At 5.5 mA the foward voltage drop would be 1 volt.
