PROBLEM TO BE SOLVED: To provide a correction data acquisition method and circuit and a receiving apparatus, capable of improving performance of the receiving apparatus including an amplifier circuit, by accurately correcting a signal output from the amplifier circuit. SOLUTION: A correction data acquisition circuit includes: at least a reference signal generator 9 which outputs a reference signal; an amplifier circuit 3 which amplifies and outputs the reference signal; an A/D conversion unit 6 which performs A/D conversion upon the amplified signal and branches and outputs the signal into two systems; a band limit filter 10 which outputs a signal of one system while performing band limiting thereon; a correction processing section 7 which acquires correction data for correcting the output of the amplifier circuit 3 on the basis of a band-limited signal and a band-non-limited signal; and a correction data storage section 8 for storing the correction data so as to refer to them.
