Patent ID: 7902881

Claim:
An output signal generating device comprising: a control circuit for generating a control signal; a reference signal generating unit for generating a reference signal; an output signal generating unit for generating an output signal according to a comparison result between the control signal and the reference signal; an output signal detecting unit for detecting the output signal based on a sampling signal; and an output signal storage unit for storing the output signal detected by the output signal detecting unit, wherein the control circuit includes a readout unit for reading out the output signal stored in the output signal storage unit, wherein the output signal storage unit includes: a primary storage unit for storing the output signal detected by the output signal detecting unit; a trigger signal generating unit for generating a trigger signal; a secondary storage unit for receiving and successively storing information on the output signal stored in the primary storage unit, the information on the output signal being to be read by the readout unit; and a transfer control unit for controlling transferring timing of the output signal information from the primary storage unit to the secondary storage unit based on the trigger signal.
