Use CMOS Transistors to bit a 4-bit Adder NAND2 Schematic symbol Implementation of a Full Adder (ES210) (carry-in) Full Adder • 2 Half Adder – XOR – AND • OR NAND-Based XOR Gate schematic symbol NAND-Based AND Gate schematic symbol NAND-Based OR Gate schematic symbol Full Adder Symbol Test Bench For the Adder Waveforms of the Full Adder Four-Bit Adder C4 is calculated last because it takes C0 8 gates to reach C4 Each FA uses 2 XOR, 2 AND and 1 OR gate. A four-bit adder uses 8 XOR, 8 AND and 4 OR gate.
