The diff-amp configuration shown in Fig. 22.39 is useful in situations where a truly differential output signal is needed. Determine the following: (a) the trans conductance of the diff-amp, (b) the AC small-signal drain currents of all MOSFETs in terms of the input voltages and g
_{m n}
(the trans conductance of an n-channel MOSFET), and (c) the small-signal voltage gain, (v₀+ - v₀_)/(v₁₊
- v_{1_}). Verify your answers with SPICE.
