Are gates and transistors the same?

“In a computer, a gate controls the flow of electric current through a circuit. The gate consists of transistors; the transistors are selected by the chip designer from two basic types (PMOS and NMOS transistors) that are found in the ubiquitous CMOS (complementary metal-oxide semiconductor) technology.

Can transistor be used in making AND gate?

The device can be used as a switch and also as an amplifier to change the values or control the passing of an electrical signal. For building an AND logic gate using a transistor we would be using BJT transistors which can be further classified into two types: PNP and NPN – Bipolar Junction Transistors.

What gate is a transistor?

NAND gate
A NAND gate is made using transistors and junction diodes. By De Morgan’s laws, a two-input NAND gate’s logic may be expressed as AB=A+B, making a NAND gate equivalent to inverters followed by an OR gate. The NAND gate is significant because any boolean function can be implemented by using a combination of NAND gates.

How transistor works as a NOT gate?

A NOT gate simply inverts its input. When no voltage is present on the input, the transistor turns off. When the transistor is off, no current flows through the collector-emitter path. Thus, current from the supply voltage (Vcc in the schematic) flows through resistor R1 to the output.

How transistor works as not gate?

The operation of this circuit is simple. The input is connected through resistor R2 to the transistor’s base. When no voltage is present on the input, the transistor turns off. When the transistor is off, no current flows through the collector-emitter path.

What is bubbled OR gate?

Bubbled OR gate: The OR gate with inverted inputs is called as Bubbled OR gate which is also called as negative OR gate. NAND gate is also called as an active low OR gate since its output becomes high even if any of the input is 0. NOR GATE: The NOR gate operates like an OR gate followed by an INVERTER.

What happens when the gate of a transistor is off?

When the gate of a transistor is ON (or has a value 1) then electricity flows from the source to the sink and the transistor is said to be ON. Otherwise when the gate of a transistor is OFF (or has a value 0) then electricity does not flow from the source to the sink and the transistor is said to be OFF. The current technology used

How does a transistors work?

Transistors have the property that if a suitable voltage is applied to the base, current can flow between the collector and the emitter. This is exactly like the mechanical switches we’ve been using except that we control the switching action with voltage instead of mecahnical motion.

How does a faucet work like a transistor?

Just like a transistor, a faucet is connected to a source (the water company), the faucet drains in a sink, and the flow of water through the faucet is controlled by a gate (the knob). If the faucet knob (gate) is turned ON water flows from the source to the sink, otherwise if the faucet knob (gate)…

How many transistors are in an a transistor?

A transistor is an electronic device that has three ends: a source, a sink, and a gate. The figure below shows three individual transistors (circa 1960s). Today’s technology allows us to pack up to 1 million transistors per square millimeter (circa 2006).
