In the circuit shown, transistors Q1 and Q2 are biased at a collector current of 2.6 mA.
Assuming that transistor current gains are sufficiently large to assume collector current equal
to emitter current and thermal voltage of 26m V, the magnitude of voltage gain Vo/Vs
in the
mid-band frequency range is _____________ (up to second decimal place).

In the voltage reference circuit shown in the figure, the op-amp is ideal and the transistors Q1,
Q2,….., Q32 are identical in all respects and have infinitely large values of common – emitter
current gain $$\beta $$. The collector current (IC) of the transistors is related to their base emitter voltage (VBE) by the relation IC = IS exp (VBE/VT); where Is is the saturation current. Assume that the
voltage VP shown in the figure is 0.7 V and the thermal voltage VT=26mV
