Abstract :
A tunnel-diode amplifier is stable when the amplifier network is reduced to an arbitrary single loop and the equation given by the sum of the impedances around this loop equal to zero [ΣZ(P)=0 where p= γ +jω ] has no solution in the right-half plane (γ>0). This is equivalent to the requirement that the system determinant shall have no zeros in the right-half plane. Several authors have used this criterion. To determine analytically whether ΣZ(p) has any positive zeros is very laborious if at all possible for many practical amplifier configurations.
