Webb18 apr. 2012 · Input high, output low. If the input signal is low there won't be any base current, and no collector current. No current through R1 means no voltage drop, so that the output will be at +V. Input low, output high. This already leads a bit further, but like I said in comment to sandun the output is highly asymmetrical. Webb9 aug. 2024 · The main principle behind the working of such a regulator is that a large proportion of the change in supply or input voltage appears across the transistor and thus the utput voltage tends to remain constant. The output voltage can thus be written as. Vout = Vzener – Vbe. Webb8 dec. 2024 · In a typical HBT, N e /P b ≈ 1/10. That is, the base is heavily doped compared to the emitter, minimizing base width modulation. Therefore β max =5 x 0.1 x 3000 ≈ 1500, which is a huge number. Therefore I p = I n / β max = I n / (1500), which is negligibly small compared to I n and can be ignored. solano county apn lookup
