Circuit NotesComponenc value sensitivity is extremely critical, as are temperature coefficients and matching ofthe components. Best performa,ce is attained when perfectly matched components are used and when the gain of the amplifier is unity．To illustrate，the quality factor Q is very high as amplifier gam approaches1 with all components matched（In fact，theoretically it approaches co）but decreases toabout 12.5 with the amplifier gain at 0.98.
