Voltage Divider Bias Circuit

Objective: A. Identify the type of transistor. B. Implement the voltage divider bias circuit and find DC voltages and current values. Also determine its mode of operation. Explanation: A transistor is a solid state device made from semiconductor material with connections made at three or more points where the electrical characteristics are different. The term transistor comes from the words transfer and resistor. The term was adopted because it best describes the actual operation of transistor, the transfer of an input signal current from a low resistance circuit to a high resistance output circuit. A transistor must be properly biased in order to operate as an amplifier. DC biasing is used to establish a steady level of transistor current and voltage called the dc operating point (QPoint).Voltage divider bias provides good Q-point stability with a single polarity supply voltage. It is the most common bias circuit.
