... circuit). Such a theoretical device would have a zero ohm output impedance in series with the source. A real-world voltage source has a very low, but non-zero output impedance: often much less than 1 ohm. Conversely, a current source provides a constant current, as long as the load connected to the ...

...  When Vin=0, Vout is NOT 0 due to mismatch of transistors in real circuit design.  It is more meaningful to specify input-referred offset voltage, defined as Vos,in=Vos,out / A.  Offset voltage may causes a DC shift of later stages, also causes limited precision in signal comparison. ...

... If the input is AC a simple transformer and SMPS can do the job perfectly in almost the same fashion as step-down power supply. If the output is DC only the SMPS can step the voltage up. The principle of operation is the same as if the voltage is stepped down (by transformer or by inductor). ...

Stray voltage



Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
