A vbe multiplier is designed with equal resistances for, Ask an Expert

Engineering

A VBE multiplier is designed with equal resistances for nominal operation at a terminal current of 1 mA, with half the current flowing in the bias network. The initial design is based on β =∞and VBE =0.7 V at 1 mA.

(a) Find the required resistor values and the terminal voltage.

(b) Find the terminal voltage that results when the terminal current increases to 2 mA. Assume β=∞.

(d) Repeat (c) using the more realistic value of β =100.
