QUESTION 23: For the transistors in the circuit in Figure P11.3, the small-signal parameters are:

g_{m 2} = 390 μ A / V, g_{m 3} = 430 μ A / V, r_{o 1} = r_{o 2} = r_{o 3} = \infty

, and

r_{o 4} = r_{o 5} = 130 k Ω

. (a) Determine the differential-mode voltage gain,

A_{d} = v_{o 3} / v_{d}

and the common-mode voltage gain,

A_{c m} = v_{o 3} / v_{c m}

. (b) Determine the output voltage

v_{o 3}

if

v_{1} = 2.14 \sin ω t V

and

v_{2} = 1.88 \sin ω V V

.
