Two-Input AND Gate Using Only Two-Input NOR Gates
Standard cell libraries often favor a specific universal gate based on the underlying semiconductor technology, requiring logic synthesis tools to map fundamental operations exclusively to those available cells. Implementing an AND function using only NOR logic demonstrates the direct application of De Morgan's laws and the principle of duality.
The circuit must compute the logical AND of inputs A and B, driving the output Y high only when both inputs are high.
| A | B | Y | |-----|-----|-----| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |
Constraints
- Use only 2-input NOR gates.
- Combinational logic only.
- No constant inputs allowed.
