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.

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.

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
