Claim 6:
7. The system according to claim 5, wherein said operation modes include at least the following modes:
a high sensitive mode, in which the control unit does not apply said gate voltage to the gate electrode structure or selects and applies a gate voltage with an absolute magnitude below (0.9*Vt−Vcnp) volts, where Vt=qe·n*·A/Cg, where qe is the electron charge, n* the residual charge carrier density, A the area and Cg the capacitance of the gate and Vcnp the voltage at which the quantum capacitance is lowest, to reduce, not to increase or increase just a percentage below 35% said quantum capacitance;
a high dynamic range mode, in which the control unit selects and applies to the gate electrode structure a gate voltage with an absolute magnitude above (1.1*Vt−Vcnp) volts, to increase to a percentage above 45% said quantum capacitance; and
a trade-off mode, in which the control unit selects and applies to the gate electrode structure a gate voltage with an absolute magnitude between 0.9−(1.1*Vt−Vcnp) volts range, to increase said quantum capacitance to a percentage ranging between 35 and 45%.
