A frequency multiplier circuit based on a well-known pulse-width control loop is presented. The proposed circuit can be used to enhance the output frequency range of a phase-locked loop (PLL) by using multiple phases of the voltage-controlled oscillator. It can be used for enhancing the ...
A frequency multiplier for rectangular-wave input based on phase-locked loop (PLL) technique is described. The main feature of the proposed circuit is that the output waveform has the same duty cycle as that of the input.doi:10.1080/00207218608920878...
The VCDL is designed using a differential structure to reduce common-mode noise. The proposed frequency multiplier is fabricated in a 65nm, 1.2V TSMC CMOS process, and the operating frequency range from 10MHz to 24MHz was measured. The SSB phase noise is measured to be -125dBc/Hz at 1MHz...
Measurement of phase noise in high-precision oscillator using PLL-type frequency multiplier Measurement of phase noise using PLL is known as a highly precise method. But the method cannot be applied when the stability of the test oscillator is hig... Y Sakuta,H Mino,Y Sekine - 《Electronics ...
I am working on a Cyclone 10 lp problem using an internal PLL. I'm using the above AHDL code to configure it. The expected output is 245Mhz, since it's a 30.72MHz input and a multiplier of 8. I have checked the synthesized code and everything is routing correctly. When I put ...

PROBLEM TO BE SOLVED: To extract high frequency having a high CN ratio and to extract stable frequency at the time of forming a PLL loop based upon that high frequency by including a frequency adding means for adding the frequency of a frequency-divided output and that of an oscillation outp...
Frequency Multiplier with Delay Locked Loop -Based Clock Generator for System on Chip Applications A high-speed, low-power, and highly reliable frequency multiplier is proposed for a delay-locked loop-based clock generator to generate a multiplied clock ... G Kumar,J Prabhakar,N Raju 被引量: ...
I looked in the autamtically generated file and saw that a clock devision and multiplier parameter was created (although is specified a frequency in the megawizard): " clk0_divide_by : NATURAL; clk0_multiply_by : NATURAL; " I'd like to work with the output frequency parameter instead ...
