Amplitude of the signal voltage

Reference no: EM131018033

It is required to design a differential amplifier to provide the largest possible signal to a pair of 10-kΩ load resistances. The input differential signal is a sinusoid of 5-mV peak amplitude, which is applied to one input terminal while the other input terminal is grounded. The power supply VCC available is 5 V. To determine the required bias current I, derive an expression for the total voltage at each of the collectors in terms of VCC and I in the presence of the input signal. Then impose the condition that both transistors remain well out of saturation with a minimum vCB of approximately 0 V. Thus determine the required value of I. For this design, what differential gain is achieved? What is the amplitude of the signal voltage obtained between the two collectors? Assume α ?1.
