    [SOLVED] And-Or-Invert (AOI) for XOR gate

    Alright. My question is, I would like to design an And-Or-Invert (AOI) gate. So, is it anything wrong the way I design the gate as above? Because I see most of the AOI gate, they just involving the AND gate and NOR gate but no NOT gate is involve. I just worry there is rule on designing the...

    [SOLVED] And-Or-Invert (AOI) for XOR gate

    So, is it ok if I put 2 inverter to the 2 inputs in the AND gate? Will it violated the AOI design rule?

    [SOLVED] CMOS Transmission Gate

    Alright. Thank you very much. :smile: ---------- Post added at 17:22 ---------- Previous post was at 17:13 ---------- But, it seems weird for having both nMOS instead of one nMOS and one pMOS. Is it suppose to be like that?
