The NOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.

We can design and implement the NAND and NOR gates in different technologies such as DTL, RTL, TTL, and CMOS. This chapter deals with implementation of NAND and NOR gates using CMOS technology.

CMOS NOR Gate Circuit: Fig. 3.4 shows 2-input CMOS NOR Gate Circuit. Here, P-channel MOSFETs Q 1 and Q 2 are connected in series and N-channel MOSFETs Q 3 and Q 4 are connected in parallel.

Aug 4, 2015 · For the design of ‘n’ input NAND or NOR gate: Let’s say n = 3 In case of NAND gate, 3 pMOS will be connected in parallel and 3 nMOS will be connected in series, and other way around in case of 3 input NOR gate.

Jun 6, 2024 · NOR gate performs NOR(NOT OR) operation between two or more binary inputs and gives output binary signal. This is a combination of OR gate and NOT gate. It gives the output high(1) only when all of its inputs are low(0).

Apr 14, 2023 · NOR Gate: For two input NOR gate, if A and B are the inputs then its output Y = (A+B)’. In the NMOS network, whenever there is an OR operation between the two variables then two NMOS transistors will get connected in parallel.

Oct 12, 2022 · CMOS(Complementary MOS) logic family uses both N-channel and P-channel MOSFET devices. CMOS has greater complexity than PMOS and NMOS. However, the speed of operation is high and power dissipation is less in CMOS.

CMOS NOR Gates A CMOS NOR gate circuit uses four MOSFETs just like the NAND gate, except that its transistors are differently arranged. Instead of two paralleled sourcing (upper) transistors connected to V dd and two series-connected sinking (lower) transistors connected to ground, the NOR gate uses two series-connected sourcing transistors and ...

This example shows a CMOS NOR gate. The output is low whenever one or both of the inputs is high, and high otherwise. Click on the inputs (on the left) to toggle their state. The MOSFETs act as switches. When one of the inputs is high, the corresponding n-MOSFETs switches on to connect the output to ground.

A CMOS NOR gate circuit uses four MOSFETs just like the NAND gate, except that its transistors are diifferently arranged. Instead of two paralleled sourcing (upper) transistors connected to Vdd and two series-connected sinking (lower) transistors connected to ground, the NOR gate uses two series-connected sourcing transistors and two parallel ...
