A VBE multiplier (see Figure 1) is designed with equal resistances for operation at bias current of 1 mA with half current flowing in the bias network. The initial design is based on B=o and VBE=0.7V at 1 mA. Find the required resistor values and the biasing voltage VBB. +Vcc IBIAS ON R2 Ovo VBB RL R1 - Vcc Figure 1.
