SUMMARY

The discussion focuses on constructing complex CMOS gates, specifically NAND and NOR logic configurations. It is established that a NAND gate consists of two PMOS transistors in parallel at the top and two NMOS transistors in series at the bottom. Conversely, a NOR gate is formed by two PMOS transistors in series at the top and two NMOS transistors in parallel at the bottom. The participant seeks clarification on the rules governing the arrangement of transistors based on logical expressions.

I don't understand how he construct it. I know NAND is fromed by two PMOS in parallel at top and two NMOS in series at bottom. NOR is formed by two PMOS in series at top and two NMOS in parallel at bottom.

Like, are there any rule that says, if I see (A+B), the CMOS should be in parallel or series...?

Thank you
