The ratio of the open circuit voltage of a voltage amplifier (AV) to the short circuit transconductance of a (Gm) of a transconductance amplifier, given that both have the same value of the internal resistance (Ri) and the output resistance (R0), is
(a) Ri
(b) R0
(c) 1/Ri
(d) 1/R0
This question was addressed to me in final exam.
The origin of the question is Circuit Models for Amplifier in division Signals and Amplifiers of Electronic Devices & Circuits
