internal input impedance
1Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
2Output impedance — The output impedance, source impedance, or internal impedance of an electronic device is the opposition exhibited by its output terminals to an alternating current (AC) of a particular frequency as a result of resistance, inductance and… …
3Negative impedance converter — The negative impedance converter (NIC) is a one port op amp circuit acting as a negative load which injects energy into circuits in contrast to an ordinary load that consumes energy from them. This is achieved by adding or subtracting excessive… …

5Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… …
6Miller theorem — refers to the process of creating equivalent circuits. It asserts that a floating impedance element supplied by two voltage sources connected in series may be split into two grounded elements with corresponding impedances. There is also a dual… …
7Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… …
8Oscilloscope — This article is about current oscilloscopes, providing general information. For history of oscilloscopes, see Oscilloscope history. For detailed information about various types of oscilloscopes, see Oscilloscope types. Illustration showing the… …
9Multimeter — A digital multimeter A multimeter or a multitester, also known as a VOM (Volt Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability …
