Corrections to “Unified Theory of Linear Noisy Two-Ports” [Nov 13 3986-3997]

In Table II and eq. (57) of the above-named document [ibid., vol. 61, no. 11, pp. 3986???3997, Nov. 2013], the expression for reverse power gain is incorrect and should be replaced as given herein in eq. (1). The corrected equation (1) allows the use of amplifier y-parameters before the addition of an interstage matching network in accordance with text immediately following [1, eq. (57)]. The subsequent discussion in [1, Sec. IV-C] that includes G,sub>pr is not affected by this correction.
