In this paper, we propose a method for extracting the spectral information of a multi-gigahertz jittery signal. This method utilizes existing on-chip single-shot period measurement techniques to sample and measure the period of multiple cycles of the multi-gigahertz periodic signal for spectral analysis. Since measurements are made on the period of multiple(More)
This paper describes a novel test method for continuous-time adaptive equalizers. This technique applies a two-sinusoidal-tone signal as stimulus and includes an RMS detector for testing, which incurs no performance degradation and a very small area overhead. To validate the technique, we used a recently published adaptive equalizer as our test case and(More)
In this paper, we propose a method for extracting the spectral information of a multi-gigahertz jittery signal. This method may utilize existing on-chip single-shot period measurement techniques to measure the multi-gigahertz signal periods for spectral analysis. This method does not require an external sampling clock, nor any additional measurement beyond(More)
High performance serial communication systems often require the Bit Error Rate (BER) to be at the level of 10 or below. The excessive test time for measuring such a low BER is a major hindrance in testing communication systems cost-effectively. In this paper, we propose a new technique for accurate and efficient estimation of the BER. The proposed technique(More)
In this paper, we propose a simple technique for estimating the standard deviation of a Gaussian random jitter component in a multi-gigahertz signal. This method may utilize existing on-chip single-shot period measurement techniques to measure the multi-gigahertz signal periods for the estimation. This method does not require an external sampling clock, nor(More)
Clock and data recovery (CDR) circuits incorporating a bang-bang (BB) phase detector have been widely adopted in high-speed serial links due to their advantages in high speed implementations. However, the heavily nonlinear nature of the BB phase detector makes the analysis of the CDR loop difficult. In this paper, we propose a new technique for accurate and(More)
