A BJT operates with a collector voltage of 5V and a base voltage that varies with a small signal of ±0.2V. Analyze this system using your knowledge of small signal analysis. How would you define the Q-point and linearize around it?
💡 Hint: Identify the DC conditions carefully and remember to use derivatives for linearization.
If a small signal causes a change in the collector current to be approximately -20mA/V at the operating point, calculate the output voltage swing when the input small signal varies ±0.1V.
💡 Hint: Apply the relationship between input, output, and small signal parameters accurately.
