A BJT differential amplifier is designed with a lower supply voltage of -10V and an upper supply of +10V. Calculate the expected ICMR based on typical transistor cutoff and saturation levels (assuming V_CE(sat) = 0.2V).
💡 Hint: Think about the conditions for cutoff and saturation with respect to supply voltage.
Design a differential amplifier circuit considering ICMR for a real application where input signal fluctuates. Explain how you'll manage the design to ensure signals are not lost due to exceeding ICMR.
💡 Hint: Consider using feedback or other design techniques to maintain linear operation over the expected input signal range.
