Unformatted text preview: find the value of R for which V OUT =26mV. Problem 5 In the circuit of following figure, (a) determine the value of R1 such that this resistor carries 0.5mA. Assuming Is=5X1016 A for each diode. (b) what is the voltage drop across the current source I X . V OUT I=10mA R 10R Problem 6 The circuit illustrated in the following figure employs two identical amplifiers. The circuit model for each amplifier is also shown. Please calculate the output voltage Vout. Hint: use Thevenin equivalent circuit to simply your analysis....
