Q2. HOW TO CALCULATE POWER RATING OF ELECTRONICS COMPONENTS AND HOW THEY DESIGN?

Ans.

Power rating of electronic components is calculated based on voltage, current, and thermal considerations for safe operation.

  • Power (P) is calculated using the formula P = V × I, where V is voltage and I is current.

  • For resistive components, use P = I² × R or P = V² / R to find power dissipation.

  • Consider thermal management; components must operate below their maximum junction temperature.

  • Example: A resistor rated at 1W can safely dissipate 1 watt of power without overheating.

Q5. HOW TO INTERFACING CAN, I2C AND SPI PROTOCOLS?

Ans.

Interfacing CAN, I2C, and SPI protocols involves understanding their unique characteristics and wiring methods for communication.

  • CAN (Controller Area Network) is used for robust communication in vehicles; it requires a CAN transceiver.

  • I2C (Inter-Integrated Circuit) uses two wires (SDA, SCL) for communication; devices are addressed by unique addresses.

  • SPI (Serial Peripheral Interface) uses four wires (MOSI, MISO, SCK, CS) for full-duplex communication; it allows multiple slave...read more

Q12. HOW TO USE SI & PI?

Ans.

Signal Integrity (SI) and Power Integrity (PI) ensure reliable electronic performance by managing signal quality and power distribution.

  • SI focuses on maintaining signal quality by minimizing reflections and crosstalk, e.g., using controlled impedance traces.

  • PI ensures stable power delivery to components, preventing voltage drops and noise, e.g., using decoupling capacitors.

  • Both SI and PI are critical in high-speed digital designs to avoid data corruption and ensure system rel...read more
