Abstract
The present invention relates to an amplifier arrangement having a plurality of amplifier stages that form a series circuit. Each amplifier stage comprises a current mirror, the translation ratio of which defines the gain of the amplifier stage. Moreover, a current coupling-out element is provided in each amplifier stage, a partial current being output at said element, and the partial currents are added together in a summation element. An RSSI signal associated with the summed currents is provided at the output of the summation element. The RSSI amplifier arrangement provides constant and thermostable signal amplification, low sensitivity to overvoltages, and exhibits a low current requirement and good radio frequency properties.
