摘要： A method for obtaining field strength information from a received electromagnetic signal by a receiver unit, in which an input voltage is generated for an operational amplifier from the received signal in the receiver unit by an input resistance and an output voltage is generated 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, and hereby the input voltage is tapped at a divider node of a voltage divider and to adjust the output voltage to the reference voltage the gate voltage of the MOS transistor, operating within a nonlinear range, and connected to the divider node is changed in such a way that the forward resistance of the MOS transistor is changed substantially logarithmically and the field strength value received by the receiver unit is determined from a comparison of the value of the present gate voltage with the quantities assigned to the gate voltage values in a memory.

摘要： A method for obtaining field strength information from a received electromagnetic signal by a receiver unit is provided, whereby an input voltage for an operational amplifier is generated from the received signal in the receiver unit by means of an input resistance realized as a voltage divider circuit and an output voltage is generated by the operational amplifier by means of 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 the voltage divider circuit and, to change the input voltage at the voltage divider circuit, which has a plurality of divider nodes and a constant resistance value, a divider node is selected and a partial voltage is tapped. The field strength value received by the receiver unit is determined from a comparison of a quantity assigned to the selected divider node.
