Intrinsic: Refers to a pure semiconductor. A crystal that has nothing but silicon atoms is pure or intrinsic.

Integrator: A circuit that performs the mathematical operation of integration. One popular application is generating ramps from rectangular pulses. This is how the time base…

Integrated Circuit: A device that contains its own transistors, resistors, and diodes. A complete IC using these microscopic components can be produced in the space…

Insulated-Gate FET (IGFET): Another name for MOSFET, which has a gate that is insulated from the channel, producing a smaller gate current than in a…

Instrumentation Amplifier: This is a differential amplifier with high input impedance and high CMRR. You find this type of amplifier as the input stage of…

Input Offset Voltage: If you ground both inputs of an op amp, you will still have an output offset voltage. The input offset voltage is…

Input Offset Current: The difference of the two input currents to a diff amp or an op amp.

Input Bias Current: The average of the two input currents to a diff amp or an op amp.

Initial Slope of Sine Wave: The earliest part of a sine wave is a straight line. Tice slope of this line is the initial slope…

Ideal transistor: The first approximation of a transistor. It assumes a transistor has only two parts: an emitter diode and a collector diode. The emitter…

Ideal diode: The first approximation of a diode. The viewpoint is to visualize the diode as an intelligent switch that closes when forward-biased and opens…

Ideal approximation: The simplest equivalent circuit of a device. It includes only a few basic features of the device and ignores many others of less…

Hysteresis: The difference between the two trip points of a Schmitt trigger. When used elsewhere, hysteresis refers to the difference between the two trip points…

Hole: A vacancy in the valence orbit. For instance, each atom of a silicon crystal normally has eight electrons in the valence orbit. Heat energy…

Holding Current: The minimum current through a thyristor that can keep it latched in the conducting stage.
