均衡技术拼合DAC频率响应

资料介绍
摘要:数字 - 模拟转换器(DAC )将数字数据转换成模拟电压或电流的仪器和无线通信等应用。一个DAC的输出频率范围从DC到低于FS / 2 ,其中FS是输入更新频率。然而,对于大多数的DAC输出频率响应,推出了根据SIN (X ) / X( SINC )频率响应信封。

Equalizing Techniques Flatten DAC Frequency Response

Abstract: Digital-to-analog converters (DACs) convert digital data to analog voltage or current in applications such as
instrumentation and wireless communications. A DAC's output frequency generally ranges from DC to less than fS/2,
where fS is the input-updating frequency. The output frequency response for most DACs, however, rolls off according to
the sin(x……
