Design a pnp version of the basic three-transistor current source circuit, using a resistor to establish \(I_{\mathrm{REF}}\). The bias current is to be \(I_{O}=0.15 \mathrm{~mA}\), and the circuit is to be biased at \(V^{+}=3 \mathrm{~V}\) and \(V^{-}=-3 \mathrm{~V}\). The transistor parameters are \(\beta=40, V_{E B}\) (on) \(=0.7 \mathrm{~V}\), and \(V_{A}=\infty\).
