    • For providing a module for use of a mobile communication terminal, being small in sizes and high in reliability, and enabling with plural numbers of bands, and also a mobile communication terminal with using the same therein, canceling is conducted on transmission signal and/or noises of reception band on reception side with using a feed forward technology, for maintaining a degree of suppression of the transmission signal and/or the noises of reception band on the reception side. In this case, for achieving the cancellation of wide band signals from the transmission signal to the reception band, a delay adjusting function is used, in addition to gain and phase adjusting functions. Also, for conducting stable canceling of jamming signals, controls are conducted on the gain, the phase and the delay of a loop with using a reception SN and/or a CQI signal, etc.Further, for achieving low power consumption, a feed forward loop can be made ON/OFF depending on a level of the transmission signal.

    • In a direct conversion receiver, to cancel a DC offset generated in the baseband processing block, negative feedback arrangements comprising a gain control amplifier and a low-pass filter are respectively attached to the I and Q signal branches of the baseband block following mixer outputs. The gain control amplifier in each negative feedback circuit is gain adjusted so that the product G·B of the gain G of a primary gain control amplifier and its own gain B will be constant and thereby the DC offset is cancelled. This DC offset cancellation can be applied in a continuous receiving system with no intermittent time during a receiving operation. Capacitance elements located off-chip can be reduced to those to be used only in the low-pass filters in the negative feedback circuits, whereas many off-chip capacitance elements have been required to be inserted between each stage of gain control amplifiers in conventional baseband chains.
    • 在直接转换接收机中,为了消除在基带处理块中产生的DC偏移,包括增益控制放大器和低通滤波器的负反馈装置分别附加到混频器输出之后的基带块的I和Q信号分支。 每个负反馈电路中的增益控制放大器被增益调整,使得主增益控制放大器的增益G的乘积G·B和其自身的增益B将恒定,从而DC偏移被消除。 该DC偏移消除可以应用于在接收操作期间没有间歇时间的连续接收系统中。 位于片外的电容元件可以减少到仅在负反馈电路中的低通滤波器中使用的电容元件,而许多芯片外电容元件需要插入到常规基带中的增益控制放大器的每个级之间 链条

    • A quadrature mixer circuit and an RF communication semiconductor integrated circuit capable of suppressing variations in secondary distortion while reducing the current consumption are provided. In a quadrature mixer circuit, even if local signals different by 90 degrees inputted to the bases of I transistors and Q transistors have large amplitudes, interference is suppressed by I resistors, Q resistors, and capacitors. Also, since the capacitors are provided, changes in bias current values can be suppressed. Accordingly, variations in secondary distortion can be suppressed. Furthermore, the capacitors combine current outputs of a differential circuit formed of I transistors and the resistor and a differential circuit formed of Q transistors and the resistor. Therefore, current consumption can also be reduced.
