The VCO incorporates the transmission oscillator
and an output amplifier used to isolate the oscillator
from external influences.
In this section, we describe the experimental methods used to compare the resilience of the MEMS oscillator
to several commercially available quartz oscillators

is] the maximum charge on the node capacitor, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the white noise source spectral density in the oscillator
circuit and [DELTA][omega] is the offset frequency from the carrier.
Leeson's 1966 paper, " A Simple Model of Feedback Oscillator
Noise Spectrum," Proceedings of the IEEE, includes an equation with loaded Q multiplied by frequency offset in the denominator of an expression for noise power.
remained an elusive technological dream as research revealed its potential without actually proving its worth.
In addition, the new DCSOs can be delivered at standard and custom frequencies without the non-recurring-engineering standard costs associated with custom CRO/SAW resonator-based oscillator
The frequencies of the two oscillators
, the reference signal and the offset, must add up to the fixed reference frequency of the cavity.
These might include fluidized bed oscillators
, rotating drum coolers, fluidized bed vertical coolers or continuous rotating plow coolers.
How are various parameters of the oscillator
such as frequency, current, rise time, fall time, and duty cycle effected under high temperature operation?
For decades an accurate oscillator
utilizing a silicon resonator remained an elusive technological dream as research revealed its potential as an alternative to quartz oscillators
without actually proving its worth.
