摘要： The present invention provides a non-linear distortion detection method and a distortion compensation amplifying device capable of suppressing increase of the circuit size and the power consumption even if the signal band is widened. A signal obtained by feeding back an output of a power amplifier is sampled by an A/D converter. An equalizer of a distortion detection unit uses an input signal d(n) of a predistorter as a reference symbol to detect an equalization error e(n) of the orthogonal demodulation signal u(n). An absolute value averaging unit outputs an absolute value of the equalization error e(n) which has been temporally averaged to E(n) as a distortion value to a control unit. According to the distortion value, the control unit adaptively controls the predistorter to perform distortion compensation.

摘要： A conventional power amplifying device has a problem that when a signal band is widened, sampling frequency for distortion detection is increased and an FFT calculation amount of a distortion compensation unit is increased, which increase a circuit size and power consumption. The present invention provides a non-linear distortion detection method and a distortion compensation amplifying device capable of suppressing increase of the circuit size and the power consumption even if the signal band is widened. A signal obtained by feeding back an output of a power amplifier is sampled by an A/D converter. An equalizer of a distortion detection unit uses an input signal d(n) of a predistorter as a reference symbol to detect an equalization error e(n) of the orthogonal demodulation signal u(n). An absolute value averaging unit outputs an absolute value of the equalization error e(n) which has been temporally averaged to E(n) as a distortion value to a control unit. According to the distortion value, the control unit adaptively controls the predistorter to perform distortion compensation.

摘要： In the wafer position teaching method for a wafer carrying system, a teaching tool is mounted at a position of the container or the processing equipment where the semiconductor wafer is to be set. The teaching tool is sensed by a sensor provided at a wafer gripping portion of the robot. Prior to sensing the teaching tool by the sensor, external teaching tools mounted on a front external wall of the processing equipment are sensed by the sensor to roughly estimate the position of the teaching tool. Based on the estimated position, the sensor approaches and senses the teaching tool to obtain the position of the semiconductor wafer. Thus, the wafer position can be taught precisely and automatically without causing interference, even when the frontage of processing equipment is narrow.
