Answer the following ten questions in 2-3 sentences each, based on the provided source material.

1. List three key advantages of using Integrated Circuits (ICs) over circuits built with discrete components.
2. What are the characteristics of an ideal Operational Amplifier (Op-Amp) regarding input impedance, output impedance, and open-loop voltage gain?
3. Explain the function of an inverting amplifier and state the formula for its voltage gain. How does its output phase relate to its input?
4. What is a “virtual short” in the context of an op-amp, and how is it applied in analyzing circuits like the inverting amplifier?
5. Describe the primary function of a comparator circuit and the two possible output voltage levels it produces.
6. What is the Barkhausen criteria for a sinusoidal oscillator to produce sustained oscillations?
7. What are the two main functional blocks that are cascaded to create a triangular wave generator, and what is the role of each block?
8. Name the three main functional blocks of a Phase Locked Loop (PLL) and briefly describe the function of the Phase Detector.
9. Explain the difference between a Weighted Resistor DAC and an R-2R Ladder DAC, highlighting a key advantage of the R-2R type.
10. Compare the Flash type ADC and the Dual Slope ADC in terms of their primary characteristics, such as speed and accuracy.
