For very high frequencies, the input impedance of the stages is low. (12 words)
The input impedance is relatively high because of the small current through Q1-Q4. (14 words)
Bilateral amplifier input impedance depends on the load, and output impedance on the signal source impedance. (16 words)
The noise temperature of an amplifier refers to the noise that would be added at the amplifier's input (relative to the input impedance of the amplifier) in order to account for the added noise observed following amplification. (38 words)
Modern electrometers A modern electrometer is a highly sensitive electronic voltmeter whose input impedance is so high that the current flowing into it can be considered, for most practical purposes, to be zero. (33 words)

Example sentences (19)
Bilateral amplifier input impedance depends on the load, and output impedance on the signal source impedance.
Each antenna is alternately connected to a transmitter having a particular source impedance, and a receiver having the same input impedance (the impedance may differ between the two antennas).
High input impedance at the input terminals and low output impedance at the output terminal(s) are particularly useful features of an op-amp.
Input impedance The input stage with Q1 and Q3 is similar to an emitter-coupled pair (long-tailed pair), with Q2 and Q4 adding some degenerating impedance.
The input impedance of an infinite line is equal to the characteristic impedance since the transmitted wave is never reflected back from the end.
Also, both devices operate in the depletion mode, they both have a high input impedance, and they both conduct current under the control of an input voltage.
The common mode input impedance is even higher, as the input stage works at an essentially constant current.
The DC input resistance of the electrometer is determined solely by the leakage resistance of the capacitor, and is typically extremely high, (although its AC input impedance is lower).
The noise temperature of an amplifier refers to the noise that would be added at the amplifier's input (relative to the input impedance of the amplifier) in order to account for the added noise observed following amplification.
A specific op-amp may be chosen for its open loop gain, bandwidth, noise performance, input impedance, power consumption, or a compromise between any of these factors.
Example Q. An amplifier has an input impedance of 50 ohms and drives a load of 50 ohms.
For very high frequencies, the input impedance of the stages is low.
Meters with electronic amplifiers (all digital multimeters and some analog meters) have a fixed input impedance that is high enough not to disturb most circuits.
Modern electrometers A modern electrometer is a highly sensitive electronic voltmeter whose input impedance is so high that the current flowing into it can be considered, for most practical purposes, to be zero.
That is, the capacitive component of the input impedance inserts a DC zero and a low-frequency pole that gives the circuit a bandpass or high-pass characteristic.
The first stage consists of the matched NPN emitter follower pair Q1, Q2 that provide high input impedance.
The input impedance is relatively high because of the small current through Q1-Q4.
They should be high enough that the reactance of each is at most a tenth of the input impedance of each stage, at the lowest frequency of interest.
Up to the MHz range only "discrete" properties need be considered; e.g., a terminal has an input impedance.
