Unformatted text preview: the equation for the emitter voltage v e as a function of v tb , i b , and any appropriate resistors. (b) If i is neglected and i c = g m v = i b = i e , solve the equation obtained above for v e as a function of v tb , i e , and any appropriate resistors. (c) Use the equation obtained above to obtain and draw the Thvenin equivalent circuit seen looking into the emitter. v e = v tb i b ( R tb + r ) = v tb i e 1 + ( R tb + r ) = v tb ( i e i ) R tb + r 1 + ' v tb i e R tb + r 1 + The circuit is a voltage source v tb in series with a resistor ( R tb + r ) / (1 + ) . 2...
