Die Anfrage
“Draw a 5 V three-input CMOS XNOR using transmission-gate stages with complementary A, B, and C inputs and final output Z.”
Dann probieren SieAdd an output terminal.Add input inverters.
Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01
Decompose XNOR into two cascaded transmission-gate XOR stages and a final inverter
02
Use external complementary inputs (A, A_b, B, B_b, C, C_b) to eliminate internal inverters for the first stage
03
Include one local inverter to generate X_b from the intermediate XOR output
Suitable when designing dedicated logic blocks in full-custom CMOS, optimizing for area and speed by avoiding pre‑built standard cells.
