EE 3221 Suhas Patel June 28, 2004 Objective: To design and study the performance of a typical single-stage amplifier, with particular attention to a stable dc operating point and a desired ac gain. Circuit Diagrams:

Italicized Questions: 1.) What values did you choose? What is the dc voltage at the base? 2.5 mV. And how is it determined? With no input, we attached the voltmeter at the base to measure the voltage. Theoretically, the voltage at the base can be determined by first finding the emitter current, which is approximately equal to the collector current. Then using the IR drop across the emitter resistor and the forward voltage of the pn junction, we can find the voltage at the base. If the value of Beta is known, one can use the
