The relationship between impedance matching and gain sensitivity to the active component variations in a low-pass negative resistance amplifier
Giovanni Martinelli, Aldo Roveri · Proceedings of the IEEE · 1967
It is shown that a relationship exists between the impedance matching at the input and output ports of a reciprocal negative-resistance low-pass amplifier and the sensitivity of its transducer power gain to the variations of the component values. When the negative resistances are more than one, the sensitivity is defined assuming an equal relative variation of their values.
