Chapter 4, Problem 4.32(choose chapter or problem)
A designer of an instrument that must operate over a wide supply-voltage range, noting that a diodes junction-voltage drop is relatively independent of junction current, considers the use of a large diode to establish a small relatively constant voltage. A power diode, for which the nominal current at 0.8 V is 10 A, is available. If the current source feeding the diode changes in the range 1 mA to 3 mA and if, in addition, the temperature changes by 20C, what is the expected range of diode voltage?
