I'm confused about this problem.
 

hi
you didn't tell about what exactly making you confuse.Standard gates are also made from transistors only.Nand contains 2 Nmos and 2 Pmos,exactly the case with Nor.so transistor optimisation results in optimisation of Std gates also.
Plz go through any basic Digital VLSI book like(Wasete, Rabey)
 

standard cells are basically contains transitors only
smith_kang give some points. and or nand nor xor latch flipflop are basic std cells .
 

If you are doing digital IC design, you are more related with stand cell, such as those cells in the timing library (*.lib and *.db).
You can not adjust the W/L of the transistor, you
just can select those stand cell with different driving
strength (X2, X4....)

For the analog design, you are facing many transitors. You directly adjust the W and L for different transistor...

For the RF, you just have several transistor to
play with... W/L also can be adjusted.

Hope this help you.

Best Regards,
Tony
 

Hi

1 Not gate = 2 Transistors (1 Pmos + 1 NMos)
1 NAND gate = 4 Transistors (2 Pmos + 2 Nmos)
1 NOR gate = 4 Transistors (2 Pmos + 2 Nmos)

Except Not gate, any other standard basic gate contain 4 transistors.
 

hi

I think u r kidding. ur logic gates are madeup of transistors. there is no other relation
