Four-terminal-pair impedances and scattering parameters
Measurement Science and Technology, 2003The calibration of modern automatic RLC bridges requires a set of impedance standards. Each standard needs in turn a calibration, i.e. the knowledge of its four-terminal-pair impedance Z4TP at frequencies up to 10–100 MHz—frequencies beyond the capabilities of standard metrological setups for impedance traceability (transformer bridges). It is possible

Four-terminal resistance of a ballistic quantum wire
Nature, 2001The electrical resistance of a conductor is intimately related to the relaxation of the momentum of charge carriers. In a simple model, the accelerating force exerted on electrons by an applied electric field is balanced by a frictional force arising from their frequent collisions with obstacles such as impurities, grain boundaries or other deviations ...

Quasi-Balance Four-Terminal Resistance Bridge
IEEE Transactions on Instrumentation and Measurement, 2015A kind of quasi-balance four-terminal ac resistance bridge has been constructed. The electronic inductive voltage divider provides high accurate voltage ratios for the bridge at a wide frequency range from 20 Hz to 10 kHz. The Wagner network with electronic circuit containing followers and amplifiers makes the voltage ratio unaffected by internal ...

Four-Terminal Phase-Coherent Conductance
Physical Review Letters, 1986A conductance formula for a sample of arbitrary shape with four terminals is derived to describe transport in the limit where carriers can traverse the sample without suffering phase-destroying events. The Onsager-Casimir symmetry relations are deduced.

Four-Terminal FinFET Device Technology
2007 IEEE International Conference on Integrated Circuit Design and Technology, 2007One of the biggest challenges for the VLSI circuits with 32-nm-technology nodes and beyond is to overcome the issue of catastrophic increases in power consumption due to short-channel effects (SCEs). Fortunately, "independent" double-gate (DG) FinFETs (named "4-terminal-FinFET" because of its four terminals; source, drain, gate 1 and gate 2) have a ...

Four-terminal analysis of the Hall generator
IRE Transactions on Electron Devices, 1961The four-terminal parameters of the Hall generator are derived and then used to develop expressions for input impedance, output impedance, current gain, and voltage gain. The theoretically determined expressions are then verified for a Hall generator using indium antimonide.

A structure that contains a geometrical discontinuity is designated as a four-terminal, or two-terminal-pair, waveguide structure if it comprises an input and an output region each in the form of a waveguide propagating only a single mode. The over-all description of the propagating modes is effected by representation of the input and output waveguides
