The development started with hundreds of thousands of transistors in the early s, As of [update] , transistor counts continue to grow beyond ten billion transistors per chip. Multiple developments were required to achieve this increased density. Manufacturers moved to smaller design rules and cleaner fabrication facilities so that they could make chips with more transistors and maintain adequate yield.

Electronic design tools improved enough to make it practical to finish these designs in a reasonable time.

Modern VLSI devices contain so many transistors, layers, interconnections , and other features that it is no longer feasible to check the masks or do the original design by hand.

Instead, engineers use EDA tools to perform most functional verification work. Microprocessor chips passed the million-transistor mark in and the billion-transistor mark in Through a combination of large size and reduced packaging, WSI could lead to dramatically reduced costs for some systems, notably massively parallel supercomputers.

The design of such a device can be complex and costly, and building disparate components on a single piece of silicon may compromise the efficiency of some elements.

This has led to an exploration of so-called Network-on-Chip NoC devices, which apply system-on-chip design methodologies to digital communication networks as opposed to traditional bus architectures. A three-dimensional integrated circuit 3D-IC has two or more layers of active electronic components that are integrated both vertically and horizontally into a single circuit. Rectifier 3.

Define capture range of PLL. The range of frequencies over which the PLL can acquire lock with an input signal is called the capture range. This parameter is also expressed as percentage of f0. What are one, two and four quadrant multipliers?

The quadrant defines the applicability of the circuit for bipolar signals at its inputs. First — quadrant device accepts only positive input signals, the two quadrant device accepts one bipolar signal and one unipolar signal and the four quadrant device accepts two bipolar signals. Calculate the free running frequency. Why VCO is called voltage to frequency converter?

VCO is also called as voltage to frequency converter because the frequency of oscillations can be controlled by an externally applied dc voltage. In what way VCO is different from other oscillators. Mention any two application of Timer in Monostable mode.

What are the operating modes of PLL? What will be the frequency of the PLL output? What are the different stages of operation in a PLL? Find resolution. Define: lock range When PLL is in lock, it can trap freq changes in the incoming signal. The range of frequencies over which the PLL can maintain lock with the incoming signal is called as lock range. State why the phase detector output in a PLL should be followed by a low pass filter. The high frequency component is removed by LPF and the difference frequency only produced at the output.

The LPF not only removes the high frequency components and noise but also controls the dynamic characteristics of PLL. These characteristics includes capture and lock range, bandwidth and transient response.

What is an isolation amplifier? An isolation amplifier is an amplifier that offers an ohmic or electrical isolation between its input and output terminals. Isolation amplifiers are often used when there is a very large common mode voltage difference between input and output. Name the various protection circuits used for series voltage regulators. Why do switching regulators have better efficiency then the series regulator?

In series regulator the pass transistor is operated in its linear region to provide a controlled voltage drop across it with a steady DC current flow. Hence the power transmitted across the pass device is in discrete pulse rather than as a steady current flow. The pass device is operated as a low impedance switch. When the pass devices is at cut-off, there is no current and dissipates no power.

When the device is in saturation, negligible voltage drop appears across it. What is an optocoupler? In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is "an electronic device designed to transfer electrical signals by utilizing light waves to provide coupling with electrical isolation between its input and output". What is the function of a voltage regulator? A voltage regulator is an electronic circuit that provides a stable dc voltage independent of the load current, temperature and ac line voltage variations.

What is the principle of switch mode power supplies? This give improved efficiency over series regulators. State the need for protection diodes in voltage regulators based on LM regulator? State the need and advantages of Isolation Amplifiers? Needs: Isolation amplifier is used when amplifiers of very high common mode voltage capabilities, high isolation resistances and high common mode rejection are required.

Advantages: An isolation amplifier is an amplifier that offers an ohmic or electrical isolation between its input and output terminals. Differentiate between linear and switching regulator.

Write the expression for output voltage in LM Name two application of isolation amplifier. Isolation amplifiers are used to allow measurement of small signals in the presence of a high common mode voltage.

Specifications of 1, volts and more are common. The CMRR specification defines the degree to which the common mode voltage will disrupt the normal mode component measurement, and therefore affect measurement accuracy. Define load regulation.

Load regulation is defined as the change in output voltage for a change in load current. It is expressed in millivolts or as a percentage of the output voltage. List the characteristics of opto coupler. Define ripple rejection with respect to voltage regulators. It is defined as the ratio of the r.

It is expressed in decibels DB. What is meant by thermal shutdown applied to voltage regulators? The current limiting circuit will protect the chip from excessive load current.

Because of the thermal shutdown and current limiting, the IC voltage regulator chip is almost indestructible. What is the purpose of having input and output capacitors in three terminal IC regulators? A capacitor connected between the input terminal and ground cancels the inductive effects due to long distribution leads.

The output capacitor improves the transient response. What are the advantages of IC voltage regulators? With a neat diagram, explain working principle of switch mode power supply.
