倍频器(frequency multiplier)使输出信号频率等于输入信号频率整数倍的电路。输入频率为f1,则输出频率为f0=nf1,系数n为任意正整数,称倍频次数。 2023-04-24 10:34:59 锁相环可不可以用于倍频非周期信号? 锁相环可不可以用于倍频非周期信号? 锁相环(Phase Locked Loop,简称PLL)是一种常用的电子电路,可以用来锁...
It should also be noted that the feedback is not limited to a frequency divider. This element can be other elements such as a frequency multiplier, or a mixer. The multiplier will make the VCO output a sub-multiple (rather than a multiple) of the reference frequency. A mixer can translat...
A 20 GHz fully integrated phase-locked loop(PLL) frequency multiplier is implemented in TSMC(TSMC is the abbreviation of Taiwan Semiconductor Manufacturing Company Limited, which is a specialized process name in integrated circuit.) 65 nm CMOS(CMOS is the abbreviation of Complementary Metal Oxide ...
The PLL we have been studying is a 1 kHz bandwidth 4th order loop. This PLL is used as a frequency synthesizer that tunes from 39 to 69 MHz in 100 kHz steps. The reference frequency is equal to the step size, 100 kHz. Therefore N varies from 390 to 690. Integrator Output Voltage Gi...
PLL (Phase Locked Loop): It is a phase-locked loop or a phase-locked loop, which is used to unify and integrate clock signals to make high-frequency devices work normally, such as memory access data. PLL is used for feedback technology in oscillators. For many electronic devices to work...
Low-pass filter. A kind ofloop filterthat attenuates the high-frequency alternating current (AC) component of the input signal to smoothen and flatten the signal to make it more DC-like. Here, the phase detector functions as ananalogmultiplier, the voltage-controlled oscillator as againblock,and...
An improved phase locked loop (PLL) includes a frequency multiplier and a voltage controlled oscillator (VCO). The VCO includes a control circuit for automatically adjusting its initial free-running frequency in response to changes in an integer divider value. The adjusting is done so that the fr...
As a black box, the PLL can be viewed as a frequency multiplier. A PLL is employed when there is the need for a high frequency local oscillator (LO) source. Example applica- tions are numerous and include wireless communications, medical devices and instrumentation. Figure 1 shows the ...
