Abstract
A bandwidth estimator circuit for an analog to digital converter. The bandwidth estimator computes a bandwidth estimate of an analog signal and includes: an amplitude averaging block configured to determine an average change in amplitude of N samples, a delta time block configured to determine a minimum time difference; a peak voltage block configured to determine the maximum magnitude; a peak to root mean square block configured to determine a ratio of a peak voltage to the root mean square of the magnitude; a bandwidth estimator block configured to compute a product of a ratio of the average change in amplitude to the minimum time difference, multiplied by a ratio of the peak voltage to the root mean square, squared, to the peak voltage multiplied by a constant; and a parameter adjustment circuit configured to modify sampler parameters controlling an analog signal sampling rate. Methods are described.
