11.1.2 器件命名规则

11.1.2.1 技术参数定义

邻载波泄漏比 (ACLR):为与峰值平均比为 12dB 的载波之间存在 5MHz 偏移的 3.84MHz 带宽中测得的 3.84Mcps 3GPP W-CDMA 输入信号而定义

模拟和数字电源抑制比(APSSR 和 DPSSR):定义为 IOUT 变化量与相对于 IOUT 电流理想值标准化的电源电压变化量之比的百分比误差

微分非线性 (DNL):定义为数字输入编码变化 1 LSB(理想值)时对应的模拟输出变化

增益漂移:定义为环境温度 (25°C) 下的增益值与整个工作温度范围内的增益值之间的最大变化量(以 ppm/°C 为单位,相对于满量程范围 (FSR))

增益误差:定义为测得的满量程输出电流与理想的满量程输出电流之比的百分比误差 (FSR%)

积分非线性 (INL):定义为实际模拟输出与理想输出的最大偏差,取决于在零与满量程刻度之间绘制的直线

互调失真 (IMD3):双频 IMD3 定义为三阶互调失真与任一基频输出之比(以 dBc 为单位)
