an4 standard cell family

4-I/P AND gate

UP PREV NEXT

an4 symbol

There are two versions of these AND gates. The v0 cells have been designed for high speed, and the v4 cells for low power. For both versions, the output inverter P:N transistor ratio is 2 and the 4-NAND gate transistor ratio is 2.5, which is close to the fastest ratio. The gain between the first and second stages is high for the v0 cells giving a gate optimised for speed. The gain in the v4 cells is set to 4, more suitable for a low power option.
