Question

PRELAB: 1. From the data sheets, find the expected B of the transistors 2SC3067 and 2N3906 when Ic 2mA and the expected r, of the 2N3906 when Ic = 2mA 2. Using the current source model below Let Li be the current through RL1 Find an Connect a resistor Ri across the output terminals expression for Iui in terms of the current Is and the resistances in the circut Replace Ru1 with Ra: (a different resistor). Find an expression for l: (the current through Re:) in . terms of the current Is and the resistances in the circuit . Derive an expression for R in terms of Lu., IL. R, and Ru (Hint Combine the expressions above) Rs Practical Current Source Model For the standard current source in Figure 4, find Vee so that IREF Read the data sheets of the LM334 2mA 3. 4.
