Why passive component has better drift characteristics than active components had?
I think that the unseen context of the quote needs to be revealed to be able to adequately refer to it in your question. The quote appears to be talking about telephone lines and this suggests to me that the quote is meaningless without more context. Moving away from the quote....
In short, passive components don't suffer from anything like the problems that transistors and diodes suffer from. Diodes and transistors have very non-linear characteristics (e.g. forward diode conduction V/I ratio) and these &quot;characteristics&quot; are very much temperature affected at the atomic level and are uncompensatable other than by using high gain and feedback to linearize things (as a control system would). The diode equation: -

At a very fundamental level, the temperature (in degrees above absolute zero temperature) are involved at the very heart of things. Whereas, for a resistor at the fundamental level: -
$$I_R = \dfrac{V_R}{R}$$
So, resistors very are linear and, if there is any temperature related resistance change phenomena that is purely down to how the resistor material was mixed or produced (in simple terms). In other words they are basically linear right from the start whereas diodes are just simply highly non-linear right from the start and always.
