|Title:||Improved Time-Base for Waveform Parameter Estimation|
|Published:||May 01, 2000|
|Abstract:||An improved gated-oscillator time-base and associated auto-calibration algorithm for use in a high-accuracy sampling waveform acquistion system are described. The time-base architecture consists of a stable 100 MHz gated-oscillator, 24-bit counter chain, and a clock period interpolator. The nominal, uncorrected linearity of the time-base is approximately +/-30 ps. By using an iterative, sine-fit based algorithm, the linearity has been improved to < + /-5 ps. Details of the performance and major sources of error of the time-base and correction algorithm in an equivalent time sampling system are also discussed.|
