Oscillator Transconductance
Transconductance of the oscillator indicates the gain of the oscillator. As the transconductance
increases, the gain of the oscillator circuit increases which causes the current consumption of
the oscillator circuit to increase. Also as the transconductance increases the maximum frequency
that the oscillator circuit can support also increases, or the start-up time of the oscillator
decreases.
