Abstract :
This report points out the importance of the so-called "neutral capacitance" in determining the frequency response of microwave transistors. A simple model of the emitter-base junction capacitance is also presented which leads to the value of optimum concentration gradient for minimum capacitance of the forward-bias junction.
