Simulation, measurement, and suppression of digital noise in mixed-signal integrated circuits

Creator:: Owens, Brian E.
Abstract:: Strategies for simulation and measurement of substrate noise have been analyzed using various digital and analog circuits fabricated in the TSMC 0.35um heavily doped CMOS process. The measurements validate a substrate noise coupling macromodel that has been used to obtain the simulation results. The simulations and measurements also substantiate the...

Comparison and impact of substrate noise due to clocked and clockless circuitry

Creator:: Le, Jim K.
Abstract:: Delay insensitive asynchronous circuitry provides significant advantages with respect to substrate noise due to localized switching. The differences between the substrate noise from NULL Convention Logic (NCL) and traditional Clocked Boolean Logic (CBL) are described and analyzed based on measured results. A test chip fabricated in the TSMC 0.25 um...
