Given the characteristics of a specific MOS transistor, derive its threshold voltage from the ID-VGS graph provided. Explain your reasoning.
💡 Hint: Look for the steepest slope indicating where the transistor transitions from OFF to ON.
Analyze how the W/L ratio would affect a circuit designed for high frequency versus one designed for high power. Discuss the trade-offs.
💡 Hint: Think about how a larger area might lead to better current delivery, but also to slower performance due to increased capacitance.
