    • A method of making a simulation model, includes specifying a feature factor which characterizes a pattern layout of a mask pattern, specifying a control factor which affects a dimension of a resist pattern to be formed on a substrate by means of a lithography process using the mask pattern, determining a predicted dimension of the resist pattern to be formed on the substrate by means of the lithography process using the mask pattern through the use of a model based on the feature and control factors, obtaining an actual dimension of the resist pattern actually formed on the substrate by means of the lithography process using the mask pattern, and setting the feature and control factors and the predicted dimension as input layers and setting the actual dimension as an output layer to construct a neural network.

    • When generating an RF test signal for mismatch calibration for receiver in order to calibrate reception mismatch of an I-phase signal and a Q-phase signal that are output from demodulated signal processing circuits coupled to mixers for receiving, a Tx VCO avoids covering the higher frequency of an RF received signal in an FDD system. An RF test signal generating unit generates, in a calibration mode of a mismatch calibration for receiver circuit, the RF test signal by using an oscillation output signal of the Tx VCO and other circuits, and supplies the same to the mixers for receiving via a switch. The RF test signal has a frequency within an RF reception frequency band that is higher than that of an RF transmission signal with the maximum frequency band of multiband radio frequency communications. By switching the switch in a reception mode, an output of a low-noise amplifier that amplifies the RF received signal received by an antenna is supplied to each of the mixers for receiving.
    • 为了校准从耦合到混频器进行接收的解调信号处理电路输出的I相信号和Q相信号的接收不匹配,为接收机生成用于失配校准的RF测试信号时,Tx VCO避免覆盖较高的 FDD系统中RF接收信号的频率。 RF测试信号产生单元通过使用Tx VCO和其它电路的振荡输出信号在接收机电路的不匹配校准的校准模式中产生RF测试信号,并将其提供给用于经由开关接收的混频器 。 RF测试信号具有比具有多频带无线电频率通信的最大频带的RF传输信号的RF接收频带内的频率。 通过在接收模式下切换开关,将放大天线接收到的RF接收信号的低噪声放大器的输出提供给每个混频器进行接收。
