Question

This is one question from a) to g). It asks to refer to the information from P11.39 which can be found at the end of the question for reference.

Refer to problem P11.39 on page 557. Find the voltage amplifier model for the cascade of B followed by A. (a) What is the input impedance of the cascade? (b) What is the output impedance of the cascade? (e) What is the open-circuit voltage gain of the cascade? (d) Given the values found, this particular cascade acts the most like what type of ideal amplifier? (answer in all lower-case) (e) Now find the corresponding transconductance amplifier model. What is the input impedance? (f) What is the output impedance of the model? (g) What is the short-circuit transconductance gain of the cascade? amplifieir *P11.38. Amplifier A has an input resistance of 1 M2, an output resistance of 200 Ω, and an open-circuit transresistance gain of 100 MS2 Amplifier B has an input resistance of 50 Ω an output impedance of 500 kS2, and a short-circuit current gain of 100. Find the voltage amplifier model for the cascade of A followed by B. Then, determine the corresponding transconductance amplifier model. P11.39. Repeat Problem P11.38 if the order of the cascade is changed to B - A
