Impedance Matching in the Grounded Emitter ConnectionAuthor: Leonard Krugman As in the analysis of the grounded base connection in Chapter 3, the stability factor must be less than unity for shortcircuit stability. The numerical value of δ for the typical pointcontact transistor is .
The input image resistance is defined in equation 337 as: r_{1} = . The input image resistance of the pointcontact transistor is numerically equal to. Since the quantity under the square root sign is negative, r_{1} is imaginary and cannot be built into conventional signal sources. For the typical junction transistor, r_{1 }is. The output image resistance defined by equation 341 as r_{2} = also is imaginary for the Dointcontact transistor. For the junction transistor, r_{2} is
