The diodes in the circuit of are such that at 1 mA they drop 700 mV and also have nVT 5 26 m. If, R1 5 2.0 kV, R2 5 336 V, and R3 5 1440 V, fi nd VS so that I D2 5 0.1 mA. Hint: the problem has been specifi ed so that it can be solved via the rules of thumb, and using the apply inadvertently iterations to fi nd I D3 .
