I. INTRODUCTION Voltage amplifier is designed in this paper using Fairchild semiconductor low power signal amplifier. It is available in both low power and high power package. Low power version of the transistor, 2N3904 is being used. Power supply of 16V is used for supplying power to the transistor. II. DC Analysis DC Analysis of the transistor. All the data is being used from the Fairchild semiconductors datasheet. Operating point of the transistor is being set by DC operating point.
