DC OFFSET REMOVAL CIRCUIT WITH LOW NOISE FOR WIRELESS RECEIVER

摘要

The present invention relates to a DC offset removal circuit of a wireless receiver, more particularly to a DC offset removal circuit with low noise for a wireless receiver. The DC offset removal circuit with low noise removes the noises generated from the DC offset removal circuit by including a low-pass filter between a DC offset removal unit and the input terminal of a baseband part. The DC offset removal circuit according to the invention removes noises generated by itself by including the low-pass filter at the place where the input from the baseband part reaches the DC offset removal circuit. Therefore, the DC offset removal circuit has an effect on the reduction of the total noise in the wireless receiver.
