Various arrangements for the protection rectifier and its possible applications are described in Chapter 8. Large fluctuations of the protection current can be reduced by a current-reducing resistor, R (see Fig. 15-7). This means that the pipe/ soil potential in the middle becomes less negative. A current smoothing action can be achieved with rectifiers connected to the network or by reducing losses by an inductive resistance between the transformer and bridge rectifier (see Section 8.4). 

In addition and importantly, even in non-active junctions, when the electrode Fermi level matches the molecular bridge energy levels, resonance phenomena can generate electrical behaviours similar to those of conventional electronic devices, such as rectification [86-89] and negative differential resistance (NDR) [90, 91]. 

P-type silicon piezoresistive elements in high concentration of 1020 cm-3 are used to make a bridge configuration. The resistance of those elements increases with temperature (positive temperature characteristic). On the other hand, the piezoresistive coefficient 7r44 determines the sensibility decrease with temperature (negative temperature characteristic). The temperature-compensation circuit is made by making use of these characteristics. Fig. 7.3.8 shows the principle of the temperature-compensation circuit and the concept of temperature compensation.
