摘要:
A method includes generating an input voltage for an operational amplifier from a received electromagnetic signal in a receiver unit by an input resistance and generating an output voltage by the operational amplifier by a fixed amplification factor. The input voltage is changed until the output voltage lies within a predefined interval that includes the value of the reference voltage. The input voltage is tapped at a divider node of a voltage divider. The gate voltage of the MOS transistor, operating within a nonlinear range and connected to the divider node, is changed to adjust the output voltage to the reference voltage such that a forward resistance of the transistor is changed nonlinearly. A field strength value received by the receiver unit is determined from a comparison of the value of the present gate voltage with quantities assigned to stored gate voltage values.
