The current source to be designed has the general configuration shown in Figure 10.17. The bias voltages are \(V^{+}=2.5 \mathrm{~V}\) and \(V^{-}=-2.5 \mathrm{~V}\). The bias current is to be \(I_{O}=80 \mu \mathrm{A}\) and \(V_{D S 2}(\mathrm{sat})=0.5 \mathrm{~V}\). The total power dissipated in the circuit is to be limited to \(1 \mathrm{~mW}\). Use appropriate transistor parameters.
