Challenge Problems
Push your limits with advanced challenges
Design a common base amplifier circuit with a specified gain of 150. What parameters must you consider to ensure the bandwidth is sufficient for high-frequency applications?
💡 Hint: Think about the relationship between gain, impedance, and frequency response.
Given a common gate amplifier circuit with an input capacitance of 20 pF and a source resistance of 1 kΩ, calculate the lower cutoff frequency if the designed upper cutoff frequency is 10 kHz.
💡 Hint: Resistances and capacitances interact; use their formulas wisely.
