3 Input Nand Gate Cmos. Take w n w p if m n 2m p for equal fall and rise time. See the image below.
As with the ttl nand gate the cmos nand gate circuit may be used as the starting point for the creation of an and gate. Design a 2 bit comparator compares two 2 bit words with a single output less than using the combinational design technique described in the chapter. All inputs and outputs are buffered.
Construction of pdn.
As in the case of two input and gate the same analysis can be done for the 3 input or more and gates. Cd4011b cd4012b and cd4023b nand gates provide the system designer with direct implementation of the nand function and supplement the existing family of cmos gates. Click the input switches or type the a b and c d e bindkeys to control the gates. The complete cmos nand gate is shown in figure below which is combination of pun.
