摘要： A D.C. offset canceling technique and a gain adjusting technique permitting completion of correction of D.C. offsets and gain adjustment of amplifiers for amplifying reception signals in a relatively short period of time in a radio communication system, such as a wireless LAN, are to be provided. A communication semiconductor integrated circuit (high frequency IC) has a plurality each of low-pass filters and variable gain amplifiers which are alternately connected in multiple stages, and high gain amplifier circuits for amplifying reception signals to a predetermined amplitude level while eliminating unnecessary waves. Offset cancellation values are generated by detecting in advance D.C. offsets of amplifiers for amplifying reception signals according to a set gain, and stored into a memory, and read out of the memory to cancel the D.C. offsets of the amplifiers at the time of starting reception and altering the gain. Gain setting in a high gain amplifying section for amplifying reception signals is accomplished in two steps, rough setting and precise setting.
摘要翻译：提供一种D.C.偏移消除技术和允许在诸如无线LAN的无线电通信系统中在相对短的时间段内完成D.C.偏移校正和用于放大接收信号的放大器的增益调整的增益调整技术。通信半导体集成电路（高频IC）具有多个交替连接的多个低通滤波器和可变增益放大器，以及用于将接收信号放大到预定幅度电平同时消除不必要的波的高增益放大器电路。通过根据设定的增益预先检测用于放大接收信号的放大器的DC偏移并存储到存储器中并从存储器中读出以消除开始接收时的放大器的DC偏移而产生偏移抵消值，并且改变收益。用于放大接收信号的高增益放大部分中的增益设置分两步完成，粗略设置和精确设置。
