nondegenerate amplifier

nondegenerate amplifier

[¦nän·di′jen·ə·rət ′am·plə‚fī·ər] (electronics) Parametric amplifier that is characterized by a pumping frequency considerably higher than twice the signal frequency; the output is taken at the signal input frequency; the amplifier exhibits negative impedance characteristics, indicative of infinite gain, and is therefore capable of oscillation.
