Which of these is false for a CS amplifier without a bypass capacitor compared to a CS amplifier with a bypass capacitor?
Which of these is false for a CS amplifier without a bypass capacitor compared to a CS amplifier with a bypass capacitor? Correct Answer The output resistance decreases
For a CS amplifier without a bypass capacitor, the input resistance is unchanged and output resistance increase. RI = RG for both. RO = rds with bypass capacitor and rds = rds + (1+μ) RS without a bypass capacitor. Output is still 180° out of phase compared to applied input, but the gain decreases.
