Device
Noise Analysis
Device
noise in analog/RF circuits is critical at 90nm and limits AMS/RF
performance at 45nm and below. Analog/RF designers need to understand
and overcome the increasing negative impact of device noise to
performance, signal-to-noise ratio (SNR), bit error rate (BER), and
power requirements in their circuits.
Existing
device noise analysis tools and
behavioral model based approaches are no longer sufficient to
characterize device noise in nanometer CMOS due accuracy, performance,
and capacity limitations.
The Analog
FastSPICE Platform technology
that overcomes the practical
and performance limitations of traditional device noise analysis tools.
The AFS
Platform is the only
device noise analysis
solution that offers true SPICE accuracy.

Device
Noise Analysis Advisor
The Device
Noise Analysis Advisor
(DNA
Advisor) analyzes
transient or
PSS waveforms and recommend the parameters for each
type of device
noise analysis – including parameter settings for
limited-spectrum tools. The DNA Advisor makes recommendations for the
following simulation parameters:
- Transient
noise noisefmax
- Time-domain
PSS maxacfreq
- Time-domain
pnoise maxsideband (for non-BDA simulators)
- Harmonic
balance PSS and pnoise harms (number of harmonics)
