Push your limits with advanced challenges
You are designing a circuit that requires a balance of speed and power. If using a W/L ratio of 4 gives sufficient ID but increases Cgg significantly, how might you adjust the ratio while ensuring performance?
💡 Hint: Balance the required performance metrics carefully.
Given a NMOS with a W of 500nm and L of 180nm achieving 20mA, calculate the expected current when W is adjusted to 1.5u, and explain the reasoning behind that calculation.
💡 Hint: Use the relationship of how changes in W affect ID and consider capacitance.
