Why is CMOS called complementary?

A complementary metal-oxide semiconductor (CMOS) consists of a pair of semiconductors connected to a common secondary voltage such that they operate in opposite (complementary) fashion. Thus, when one transistor is turned on, the other is turned off, and vice versa.

What is the need of complementary push pull amplifier?

Push-pull amplifiers use two “complementary” or matching transistors, one being an NPN-type and the other being a PNP-type with both power transistors receiving the same input signal together that is equal in magnitude, but in opposite phase to each other.

What is complementary symmetry push pull amplifier?

The two transistors conduct in the opposite half cycle of the input signal. As the transistors are both complement to each other, yet act symmetrically while being connected in push pull configuration of class B, this circuit is termed as Complementary symmetry push pull class B amplifier.

What is meant by push pull amplifier?

A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance both the load capacity and switching speed.

What is CMOS VLSI?

CMOS VLSI design is like a modular approach to creating ICs. Small circuit blocks are connected into larger circuit blocks which are then connected at the system level to create a complete integrated circuit. These smaller circuit blocks can be analog, digital, or mixed-signal circuits.

What is CMOS camera?

A CMOS sensor is an electronic chip that converts photons to electrons for digital processing. CMOS (complementary metal oxide semiconductor) sensors are used to create images in digital cameras, digital video cameras and digital CCTV cameras.

Why is it called a Push-Pull Amplifier?

A Push-Pull Amplifier combines two signals to form a third signal. The circuit is called a Push-Pull because one transistor pushes in one direction while the other pulls in another direction. Both transistors are NPN types in this case. A common small signal BJT is the 2N2222 NPN Transistor [low power].

Which amplifier is used in Push-Pull Amplifier?

Push-pull Amplifier is a type of power amplifier. It contains a pair of active devices such as a complementary pair of transistors. Here one transistor supply’s the power to the load from the positive power supply and the other sink’s the current from the load to the ground.

What is complementary symmetry amplifier?

In most applications where AC power is driving a load, a complementary symmetry (push-pull) power amplifier is employed. This amplifier usually has a voltage gain of one, and a large current gain. It is the most efficient configuration for transforming DC power from the power supply to the AC power driving the load.

What is the advantage of having complementary symmetry push pull amplifier?

The advantages of Complementary symmetry push pull class B amplifier are as follows. As there is no need of center tapped transformers, the weight and cost are reduced. Equal and opposite input signal voltages are not required.

Why is it called Push-Pull Amplifier?
