Q2. What is this oee calculation
Ans. 
OEE (Overall Equipment Effectiveness) is a measure of how well a manufacturing process is performing.
• OEE is calculated by multiplying Availability, Performance, and Quality percentages.

• Availability is the ratio of actual production time to planned production time.

• Performance is the ratio of actual production speed to ideal production speed.

• Quality is the ratio of good units produced to total units produced.

• OEE provides...read more

Q1. IV characterstics of CMOS inverter
Ans. 
IV characteristics of CMOS inverter show the relationship between input voltage and output current.
• CMOS inverter has two transistors - NMOS and PMOS connected in series.

• For low input voltage, NMOS is ON and PMOS is OFF, resulting in low output voltage.

• For high input voltage, NMOS is OFF and PMOS is ON, resulting in high output voltage.

• The transition between low and high output voltage occurs at the threshold voltage.

• Th...read more

Q2. Set up and hold time explain
Ans. 
Set up time and hold time are timing requirements in digital circuits to ensure proper operation.
• Set up time is the minimum time before the clock edge that the input signal must be stable.

• Hold time is the minimum time after the clock edge that the input signal must be maintained stable.

• Violating set up time can lead to incorrect data being latched.

• Violating hold time can lead to metastability issues.

• Examples: In a flip...read more
