Q4. What is CMOS Latchup
Ans. 
CMOS latchup is a phenomenon in integrated circuits where parasitic thyristors are inadvertently triggered, causing a short circuit.
• CMOS latchup occurs when a parasitic structure in the CMOS device acts as a thyristor, leading to a low-impedance path between the power supply rails.

• It can result in excessive current flow, potentially damaging the device.

• Preventive measures include layout techniques, guard rings, and pro...read more

My Diploma in Mechanical Engineering from T.J.S. Polytechnic College has laid a strong foundation for my career as a Design Engineer. The comprehensive curriculum at the college equipped me with theoretical knowledge in areas such as machine design, thermodynamics, and material science, which I have successfully applied in my professional roles. For example, during my tenure at RENAULT & NISSAN Pvt Ltd, I utilized my understanding of machine design principles to optimize vehicle production processes. Similarly, my knowledge of thermodynamics was valuable during my time at APOLLO TYRES Pvt Ltd, where I contributed to quality control initiatives. Overall, my academic background has not only provided me with technical expertise but also instilled in me a problem-solving mindset that is essential for success in the field of design engineering.
