<p>The amplifier circuit has several amplification stages forming a series circuit. Each amplification stage has a signal input (51), a signal output (52), a current mirror (54,66,67) coupling the input to the output, and a current decoupling member (55,64,65) connected to the signal input. Each stage further includes a summer element (8) to the input of which are connected the current decoupling members. The summer outputs a signal representing the power level of a high frequency signal at the input to the circuit.</p> |
