Patent ID: 7778358

Claim:
A receiver comprising: a memory for storing DC offset amounts generated by an analog circuit; an amplifier for amplifying a received signal; a DC offset amount generator for generating a first offset value to be removed from said received signal amplified at said amplifier and a second offset value to be removed from said received signal after said amplifier in combination with said DC offset amount stored in said memory; a first DC offset component-removing unit for removing said first DC offset value from said received signal before said amplifier; a second DC offset component-removing unit for removing said second DC offset value from said received signal amplified at said amplifier; and an updating unit for updating said DC offset amount stored in said memory in view of said second DC offset value generated by said DC offset amount generator; wherein a maximum value of said second DC offset value generated at said DC offset amount generator is set larger than a multiplication value of a gain of said amplifier by a minimum resolution value of said first DC offset value.
