A multi-program engineer may be working on a new silicon-gate MOSFET, and its close cousin, the MOSC, which has many commercial applications. It is the problem of an electrical engineer to step behind the curtain and witness the wizard at work. The researcher must play the role of a potted historian eager to peek, and then hurry away.
Todayâs world is full of electronic circuits, analog circuits in particular. The majority of analog circuits are based on electronic devices called resistors, capacitors, and inductors. Resistors are the most abundant electronic devices.
Suppose oneâs interested in designing a stable and accurate amplifier circuit for an electronic instrument. By stable we mean the output of the amplifier does not drift or oscillate. Since no one wants to control drift or oscillation, this circuit must be stable over a wide range of input supply voltages (0 to 3.3 volts). In addition, the amplifier must operate with its power supply very close to the nominal voltage.
A personal Audio Amplifier supplied from a computer to a pair of Sony speakers supplies background music to a small airplane that has one-way communications with the airplaneâs flight crew. As one aircraft descends into a cloudy area, the pilots can communicate with the air ganger assigned to that aircraft by depressing the speakerâs mute button and using a microphone to dictate instructions to the air ganger. d2c66b5586
