Consider the amplifier circuit shown below. Assume a transistor current gain of β = 120. The voltage VBB establishes the Q-point, and the voltage vi is a time-varying signal that produces a variation in the base current, which in turn produces a variation in the collector current and hence a variation in the output voltage vo. (a) Determine RB such that VCEQ = 1.6 V. (b) Determine the minimum and maximum input voltages, vi(min) and vi(max) such that the transistor does not enter cutoff or saturation and determine the corresponding output voltages vo(max) and vo(min) at these values of input voltage (c) What is the voltage gain Δvo/Δvi of the amplifier where Δvo ≡ vo(min)−vo(max) and Δvi ≡ vi(max)−vi(min) ? Assume VBE(on) = 0.7 V and VCE(sat) = 0.2 V.

Q. 4: Figure 4 depicts an MOS device based differential amplifier using active loads. Figure 4: (a) Draw the schematic of a similar differential pair amplifier using BJT devices. Assuming that the bias sources have infinite output resistances, find the small signal voltage gain vout/(vin1 − vin2) of the BJT based differential pair. You can use the half-circuit principle. The ac signals Vin1 , Vin2 form a balanced differential input signal pair. (b) It is given that Iss = 2 mA, Iss2 = 1 mA, VDD = 5 V, and the Early voltage VA = 50 V for all the transistors. The transistors are all identical.
