[Source of noise in crystal oscillators and peripheral circuits] First, in Figure 1 we indicate the typical types of noise generated from crystal oscillators and the peripheral circuits. generation circuits but it has wide application in instrumentation as a reference clock generator for jitter measurements. In these applications, equation 4 describes the transfer function of a “golden” PLL and the cutoff frequency is set by the gain terms in the open loop response to a ratio of ω i/1667 where ω The ringing frequency band can be calculated as f = 1/time. If t r and t f are both 5 ns, then the period can be considered to be 10 ns, and so the frequency band is 100 MHz. In general, switching frequencies tend to range from 500 kHz to 1 MHz, and so ringing occurs at frequencies that are 100 to 200 times higher. semiconductor circuits[2] and the frequency fluctuation in an oscillator[3]. In this paper, we will discuss the correlation coefficient between the phase noise and amplitude or average current fluctuation in distributed network model and in a transistor, and propose a method to reduce the noise, using the correlation. The phase measurements were 1 noise model, which allows us to analyze 1 noise in switched MOSFET circuits more accurately. Using our model, we analyze noise for the three aforementioned switched circuit examples and obtain results that are consistent with the reported measurements.
