Identify the logic function of a layout

gonsays

Hello,

I'm a Microelectronics student and I'm in a struggle to understand which logic function is associated with the following layout:

It says that the circuit has four inputs (A and B) and one output (y), in an N-WELL TECHNOLOGY.

Thank you very much in advance and I'm sorry for my basic question for you

  • The black and white example is a simple 2-input NAND gate followed by an inverter (So, a 2 input AND gate).

    The last example is not recognizable.

    There is an inverter on the left and right. But the layout in the middle is incomplete.

    I am guessing that the layout should represent a clock buffer with inverting and non inverting outputs.

    But, the transistor in the middle has not been created correctly.

    So, it's hard to say...
