GoldenGate’s unique algorithms are optimized for the challenging demands of modern
complex radio design. These demands require a simulator with capabilities not previously
available. GoldenGate addresses these demands with the ability to converge on complete
transceivers with the speed to enable full characterization prior to tape out.
MIXEr ANALYSIS
Mixers are the fundamental block for
upconversion or downconversion of signals
in a transceiver. GoldenGate efficiently ana-
lyzes the effects of this frequency translation
by accurately measuring the conversion gain,
noise figure (with and without blocking
signals), small signal noise, linearity (ip2/ip3)
and spurious responses. Furthermore, modern
low-if architectures require the lo and
carrier frequencies to be very close together.
ip3 for low-IF mixer
GoldenGate’s harmonic-balance capabilities allow the designer to automatically calculate
these metrics far more efficiently than with traditional transient techniques.
AMpLIFIEr ANALYSIS
Amplifiers have a wide range of applications, each requiring specific design tradeoffs.
GoldenGate provides the ability to properly analyze linearity, gain and efficiency
through automated analyses such as ip3/im,
large signal s-Parameters, Pin-Pout, Gain
Compression, pae, acpr, and evm. Traditional
two tone analysis is, at best, an approximation
to reality and does not offer the designer
complete characterization of the amplifier.
GoldenGate’s Envelope Transient technique
provides the necessary capability to simulate
actual digitally-modulated signals, giving
a real-world representation of the perfor-
mance prior to tape-out.
OSCILLATOr ANALYSIS
Accurate acpr and evm of qpsk
modulated signal for cdma receiver
Oscillators are used extensively in both receive
and transmit paths. Oscillators are particularly
susceptible to noise, specifically phase and
amplitude noise. Nonlinearity and periodic
variations in both the lo and signal path
create difficulties for traditional time-domain
simulators. GoldenGate’s Envelope Transient
and Harmonic Balance approaches enable a
much faster and more accurate analysis of
vco phase noise and amplitude noise sweep
