Question

At the metastable point in the Voltage Transfer Characteristics of two cascaded inverter, the voltage gain is ideally
a)zero
b)infinity
c)100V/V
d)can't determined

Answer 1

Answer:

B) Infinity

Explanation:

Since the voltage gain at the metastable point in the voltage transfer characteristics of one inverter is infinity and when two inverters of voltage gain A & B are connected in cascade manner, the gain gets multiplied and results in A*B. Here, gain of one inverter is infinity.

Hence, the ideal voltage gain of two cascaded inverters will be infinity^2 i.e. infinity.  

Answer 2

Answer:

The correct option among these four options is Infinity.

In the voltage transfer characteristics, the voltage gain at the metastable point of one inverter is infinity.

So, when two inverters with voltage gain A and B are connected in a cascade form, the gain will be multiplied, i.e., it will be A*B.

Since the gain of one inverter is infinity, and infinity * 2 equals infinity, the correct option is infinity.
