9.2 Provide a CMOS logic gate circuit that realizes the function 𝑌 = 𝐴𝐵𝐶 + 𝐴𝐵𝐶 + 𝐴𝐵𝐶 How
many transistors are required? Explore the possibility of reducing the number of the transistors required.
9.3 The voltage-transfer characteristic of a particular logic inverter is modeled by three straight- line segments in the manner shown in fig 2. If 𝑉 = 1.2 𝑉, 𝑉 = 1.3 𝑉, 𝑉 = 0.4 𝑉 and 𝑉 =
1.8 𝑉, find:
(a) the noise margins
(b) The value of 𝑉 𝑀
(C) the voltage gain in the transition region.
