How is a NOR gate logically complete?

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. NOR is the result of the negation of the OR operator.

What is MOSFET logic?

Enhancement-mode MOSFETs are used in integrated circuits to produce CMOS type Logic Gates and power switching circuits in the form of as PMOS (P-channel) and NMOS (N-channel) gates. CMOS actually stands for Complementary MOS meaning that the logic device has both PMOS and NMOS within its design.

How do you make a NOR gate for a circuit?

An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined….AND.

Input A Input B Output Q
0 1 0
1 0 0
1 1 1

What is the circuit diagram of NOR gate?

As in truth table the output of a NOR gate should be HIGH only if both the gate inputs are LOW. In any other case the output should be LOW. So if any one or both inputs are HIGH,the output of NOR gate will be LOW….Circuit Diagram and Working Explanation.

A B Output
0 0 1
0 1 0
1 0 0
1 1 0

Which MOSFET does not have channel?

In Depletion MOSFET channel is initially formed whereas in Enhancement MOSFET it is not.

Why NOR gate is a universal gate?

The NOR gate and NAND gate are universal gates. This means that you can create any logical Boolean expression using only NOR gates or only NAND gates. In practice, this is advantageous since NOR and NAND gates are economical and easier to fabricate than other logic gates.

How do you prove that a NOR gate is a universal gate?

One NOR input pin is connected to the input signal A while all other input pins are connected to logic 0. The output will be A’. Thus, the NOR gate is a universal gate since it can implement the AND, OR and NOT functions.

How do you convert NOR to NAND?

To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.

What is the output voltage of the n-channel MOSFET?

The output voltage V 0 is then at 0 volt (logic 0 state) is applied at the input, the n-channel MOSFET Q2 is turned ON (with zero steady current) and Q1 is turned OFF. The output voltage V 0 is at -V DD (logic state 1).

What happens when the input voltage of a MOSFET is zero?

When the input voltage, ( V IN ) to the gate of the transistor is zero, the MOSFET conducts virtually no current and the output voltage ( V OUT ) is equal to the supply voltage V DD. So the MOSFET is “OFF” operating within its “cut-off” region.

What is the use of MOSFET in power supply?

Power MOSFETs can be used to regulate DC motors. MOSFETs are used in the design of the chopper circuit. MOSFETs operate at greater efficiency at lower voltages. Absence of gate current results in high input impedance producing high switching speed.

What is low threshold type power MOSFET?

Low threshold type power MOSFETs may not switch “ON” until a least 3V or 4V has been applied to its gate and if the output from the logic gate is only +5V logic it may be insufficient to fully drive the MOSFET into saturation.
