1. Why are ICs so cheap?
ICs (Integrated Circuits) are cheap because they are mass-produced using automated fabrication techniques on a single silicon wafer, allowing thousands of ICs to be created at once. The small size and efficient manufacturing process significantly reduce cost per unit.
2. Why do ICs require low power?
ICs require low power because of their miniature size and the use of low-power semiconductor components like transistors and diodes. The compact layout reduces the power needed to operate internal circuitry, making them ideal for battery-powered and energy-efficient devices.
3. Why can’t we produce ICs of greater power?
We can’t produce ICs of greater power because high power generates more heat, and the small size of ICs limits heat dissipation. This can damage the IC or reduce its efficiency. Therefore, high-power applications still rely on discrete components with better cooling and heat-handling capabilities.
4. Why are ICs more reliable than discrete assembly?
ICs are more reliable than discrete assemblies because all components are fabricated in a controlled environment on a single chip, eliminating manual soldering and interconnections that are prone to errors, wear, and physical damage.
5. Why is DIL IC package more popular?
DIL (Dual In-line Package) ICs are popular because they are easy to handle, insert into sockets or PCBs, and provide a stable and reliable connection. Their standardized pin layout simplifies circuit design and manufacturing.
6. What are Hybrid Parameters?
Hybrid parameters, commonly referred to as h-parameters, are a set of four electrical values used to describe the behavior of linear two-port networks, especially transistors in small-signal analysis. They are called “hybrid” because they involve a mix of units: resistance (ohms), conductance (mhos), and dimensionless gain.
7. What are the Limitations of H Parameters?
The limitations of h-parameters include their restriction to small-signal linear analysis, meaning they are not accurate for large signals or nonlinear behavior. They are also frequency-dependent, so values change with signal frequency. Additionally, h-parameters are not very convenient at high frequencies due to the difficulty in measuring reverse voltage gain and output admittance precisely.
