Unformatted text preview: BIAS is 10V, what value should the resistor be to make I OUT equal to 10mA? Draw the circuit labeling all currents and voltages. Assume Beta=100, V BE =0.7, and that the opamp is ideal. 2 Problem 3* : Find the voltages V x and V y . Assume a constant voltage drop model for the diode and = 100 for the transistor. Figure 3 Problem 4 : Here NPN and PNP transistors work together to form a buffer. Assuming Beta=100 and V BE =0.7V, solve for the conditions below showing your work and justifying your assumptions. Figure 1: TwoTransistor Voltage Buffer 4.1) What is V OUT when I OUT =0? 4.2) What is V OUT when I OUT =10mA?...
