RECEIVING CIRCUIT, RECEIVING METHOD, AND RADIO COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress saturation of an input level of a signal for a circuit such as ADC or the like.

SOLUTION: A receiving circuit determines whether or not the input level of a signal exceeds a predetermined threshold value concerning each of a plurality of amplifiers which are a fixed gain multistage-connected in series. Further, the receiving circuit generates a control signal indicating the use of a signal outputted from an amplifier which is at one preceding stage of the amplifier which is determined that the input level exceeds the predetermined threshold value to output the generated control signal.
