SEMICONDUCTOR APPARATUS AND RADIO COMMUNICATION APPARATUS |
摘要 |
A semiconductor apparatus that can detect the amplitude level of harmonics is provided. A semiconductor apparatus 10 includes a common mode detector circuit 11 that detects AC signals in a common mode, and a detector circuit 12 that detects the amplitude level of an even-order harmonic output from the common mode detector circuit 11. The common mode detector circuit 11 combines AC signals being differential signals in common mode, thereby cancelling out odd-order harmonics to obtain direct current and even-order harmonics. The detector circuit 12 detects the amplitude level of the even-order harmonics from a signal obtained by the common mode detection, and outputs the detected amplitude level. |
