Created by Tony R. Kuphaldt, this chapter of All About Circuit's third volume on Semiconductors describes amplifiers and active devices. The chapter is divided into seven sections: From electric to electronic, Active...

Animation of an op-amp amplifier with a current input. This is a "transimpedance amplifier"-- an amplifier with a current input and a voltage output, constructed using an op-amp. Since the input current to the op-amp is...

6.002 Circuits and Electronics is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. 6.002 is in the core of department...

This animated gif illustrates the changing voltages a conventional inverting amplifier when it receives input from a current source rather than a voltage source. Notice that the input resistor does not offer any...
