Abstract
A burst receiving circuit and a control method thereof whose unstable state of an output is able to be avoided without bringing about the decrease of the receiving level sensitivity and the deterioration of the output duty are provided. An offset which corresponds to the size of a receiving signal is given to the receiving signal and the offset is made to “0 ” at the time when the burst signal is received and the burst signal is taken out by shaping the receiving signal given offset based on a predetermined threshold value. And the offset is continued to be “0” until predetermined time has passed after finishing the burst signal. The offset is kept in “0” during the time from the start of the burst signal until predetermined time has passed after the finishing of the burst signal or until the finishing of the burst signal informed by the outside.
