in paper {A 23.4 mW 68 dB Dynamic Range Low Band CMOS Hybrid Tracking Filter for ATSC Digital TV Tuner Adopting RC and Gm-C Topology} in section IV is written :{the com-posite second-order (CSO) distortion is not important in the filter for only ATSC terrestrial standard because there exist a
few channels in terrestrial application. In addition, the gener-ated IMD2 of the filter is high-pass filtered and blocked by ac coupling capacitors located between the filter and the following block.} what is the AC coupling circuit? why they didn't show in the paper?
