One more thing and then we'll be done with the theory and into the practice. A BJT transistor will cause a drop in voltage between the collector and the emitter even when it is saturated (it isn't a perfect conductor). This voltage drop is called out in the data sheet as V ce (sat). Typically, this will be between .2 and 1 volts for silicon ... Free 100 pp osu
The output impedance of a device can simply be determined. We use a load resistance R load, to load the signal source impedance Z source.The output voltage is open initially without load as open-circuit voltage V 1 (Switch is open, that means R load is infinity) and then measured as V 2 under load with R load at point IN (Switch is closed).
Nov 23, 2019 · A transistor multimeter can tell you how much current or voltage goes through a transistor in a circuit. These transistors are used with diodes and semiconductors for letting electricity flow in a certain direction. Identify symptoms when you need to check or replace these elements.

While the methods utilized gave reasonably good answers, more precise design requires the use of BJT and FET models or equivalent circuits. The models we adopt are the hybrid parameter or h-parameter model and the y-parameter model. These transistor parameters can in general be obtained from manufacturer’s data sheets.
