7.35 An npn BJT with grounded emitter is operated with VBg = 0.700 V, at which the collector current is 1 mA. A 2- k2 resistor connects the collector to a +5-V supply. What is the resulting collector voltage V? Now, if a signal applied to the base raises vBE to 705 mV, find the resulting total collector current ic and total collector voltage ve using the exponential ic-vBE relationship. For this situation, what are vhe and v.? Calculate the voltage gain v/vbe- Compare with the value obtained using the small-signal approximation, that is, -gmRc.
