    • Embodiments of the present invention provide systems, devices and methods for detecting the RMS value of a signal. The RMS detector uses multiple variable-gain stages and internal gain control to generate an RMS output signal based on an arbitrary signal input. This RMS detector significantly reduces the signal swings seen on a squarer within prior art RMS detectors and reduces the detector's dependency on DC offsets at low signal levels and overload errors at high signal levels. Embodiments also improve the accuracy of the RMS detector within large dynamic signal ranges by obviating the operation of a squarer in saturation or out of the squaring region. Accordingly, embodiments of the present invention are able to more accurately detect RMS values on a signal, operate over relatively higher signal ranges, and better function within different signal modulation schemes, particularly those with large peak-to-average ratios.
    • 本发明的实施例提供用于检测信号的RMS值的系统,装置和方法。 RMS检测器使用多个可变增益级和内部增益控制,以产生基于任意信号输入的RMS输出信号。 该RMS检测器显着降低了现有技术RMS检测器中平方值上看到的信号摆幅,并降低了检测器对低信号电平下的直流偏移和高信号电平下的过载误差的依赖性。 实施例还通过消除饱和度平方仪的运行或平方区域的方式,在大动态信号范围内提高RMS检测器的精度。 因此,本发明的实施例能够更精确地检测信号上的RMS值,在相对较高的信号范围内操作,以及在不同的信号调制方案中更好的功能,特别是具有大的峰均比的那些。
