多电平幅度信号传输接收器
摘要：
一个实施方式涉及一种用于在每个符号周期至少包括三个幅度电平的多电平幅度信号传输的接收器电路。该接收器电路包括峰值检测器、参考电压生成器和比较器电路。该峰值检测器被布置为检测该多电平幅度信号的峰值电压，并且该参考电压生成器使用该峰值电压来生成多个参考电压。该比较器电路使用该多个参考电压来检测该多电平幅度信号的幅度电平。还公开了其他实施方式和特征。
摘要（英）：

One aspect relates to a receiver circuit for multi-level amplitude signaling which includes at least three amplitude levels for each symbol period. The receiver circuit (200) includes a peak detector (204), a reference voltage generator (206), and a comparator circuit (208). The peak detector (204) is arranged to detect a peak voltage of the multi-level amplitude signal, and the reference voltage generator (206) uses the peak voltage to generate multiple reference voltages. The comparator circuit (208) uses the multiple reference voltages to detect an amplitude level of the multi-level amplitude signal. Other aspects and features are also disclosed.
