“Draw a 5 V three-input CMOS XNOR using transmission-gate stages with complementary A, B, and C inputs and final output Z.”
Prova alloraAdd an output terminal.Add input inverters.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
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.
