Analyze a BJT circuit where the base current is 20 µA, and the current gain (β) is 100. What is the expected collector current?
💡 Hint: Remember the relation of current gain in BJTs.
Given a BJT with a V_BE of 0.7V and a collector saturation current (I_S) of 10 nA, calculate the collector current at room temperature (approximately 25°C).
💡 Hint: Still using the diode equation, keep an eye on exponential growth!
