摘要:
An input digital signal is converted to an analog signal using a main digital to analog converter (DAC) and a sub DAC. An offset value is subtracted from the input digital signal to generate an offset adjusted digital signal. The main DAC converts the offset adjusted digital signal to a first analog signal. A second digital signal is generated based on the offset value and a correction factor determined, at least in part, during calibration of the main DAC. The sub DAC converts the second digital to a second analog signal, which when combined with the first analog signal, provides an analog representation of the input digital signal.

使用主数模转换器(DAC)和子DAC将输入数字信号转换为模拟信号。 从输入数字信号中减去偏移值,以生成偏移调整数字信号。 主DAC将偏移调整后的数字信号转换为第一个模拟信号。 基于偏移值和至少部分地在主DAC的校准期间确定的校正因子来生成第二数字信号。 子DAC将第二数字转换为第二模拟信号,当与第一模拟信号组合时,其提供输入数字信号的模拟表示。
