9.85 The differential amplifier of Fig. 9.31(a) is found to have a differential short-circuit transconductance of 2 mA/V. A differential input signal is applied and the output voltage is measured with a load resistance RL connected. It is found that when RL is reduced from ∞ to 25 kΩ, the magnitude of the output signal is reduced by half. What do you estimate Ro and Ad (with RL disconnected) to be?
