Demodulation Capabilities of a DSSS Super-Regenerative Receiver Design How-To 2/26/2002 Post a comment The super regenerative circuit has found use for many years in AM and, sometimes, FM receivers. F.X. Moncunill Geniz and colleagues from the UPC Department of Signal Theory and Communications, Spain, show how to use this venerable circuit for direct sequence spread spectrum (DSSS) signal detection.
MCM and BGAs Characterization using Planar EM Simulation Design How-To 2/1/2002 Post a comment When designing at multi-GHz frequencies, you need to include accurate IC-package models and analysis. Agilent's Jim DeLap reviews MCM and BGA technologies, simulation issues, and EM simulator requirements, along with several practical simulation examples.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
