(a) What input bias point should be chosen for the amplifier as shown to provide the maximum possible linear input signal magnitude? What are the maximum input and output signal amplitudes? (b) What is the voltage gain if the amplifier input is biased at VID = −1.0 V?
The characteristics curve is shown below:
(a)
For the given graph we can observe that the range of the linear input is between 1.5 volts to -0.5 volts and during this period the gain is gain.
The maximum possible linear input signal magnitude will be the mean of the maximum and the minimum range, the calculation is shown below:
The maximum input voltage is calculated as shown below:
Thus, the maximum input and output signal amplitudes are given as:
