An analog adaptive notch filter implementation at 54.1 MHz is presented in this paper. The analog circuit is implemented using discrete components. Implementation issues such as components phase shift and DC offset are discussed and solution for them are proposed. In addition, effect of frequency offset between reference and input signal is discussed. The implemented circuit has −3 dB bandwidth of...
In VLSI systems, channel bandwidth limitation becomes a crucial problem as the required data rate communication increases, as high-frequency channel loss significantly degrades transmission performance. In this paper, we compare non-return-to-zero (NRZ) binary and 4-PAM (pulse amplitude modulation) coding techniques for serial links by fabricating a test board of a micro-strip line. By extracting...
We present a generic method for analyzing the effect of process variability in nanoscale circuits. The proposed framework uses kernel and a generic tail probability estimator to eliminate the need for a-priori density choice for the nature of circuit variation. This allows capturing the true nature of the circuit variation from a few random samples of its observed responses. The data-driven, non-parametric,...
