1896 Nat. Sci. May 290 The tendency to ‘super-regeneration’ he found to be greater the nearer the proximal end of the limb the amputation was made.

1963 Copeia 572/1 The superregeneration of amphibian hind limbs in nature can result from wounds produced by the bites of other animals.

2004 Philos. Trans. (Royal Soc.) B. 359 800/1 [Retinoic acid] first came into prominence when it was shown that it causes ‘superregeneration’ in those organisms that can already regenerate, namely the Urodele amphibians.

1922 Q.S.T. July 7/1 At a meeting of the Institute of Radio Engineers, Edwin Howard Armstrong on June 7th gave his new invention of super-regeneration to a tense and expectant audience.

1922 E. H. Armstrong in Proc. IRE 10 244 This new result is obtained by the extension of regeneration into a field which lies beyond that hitherto considered its theoretical limit, and the process of amplification is therefore termed super-regeneration.

1943 F. E. Terman Radio Engineers' Handbk. ix. 664 Receivers employing superregeneration find their chief usefulness in the wavelength range 0·5 to 10 meters.

1975 R. L. Shrader Electronic Communication (ed. 3) xviii. 435/2 This type of superregeneration is often produced in RF amplifiers and is characterized by a wide band of spurious signals that it generates.

2001 U. L. Rohde & J. C. Whitaker Communications Receivers (ed. 3) i. 65 The bandwidth is extremely wide, so that superregeneration is not suitable for many applications.
