This paper presents a more complex algorithm with Verilog-HDL, which based on the dual-modulus preseted decimal frequency divider. This algorithm can not only increase the accuracy of decimal frequency divider.
Hi plz bare with me as i am a bit of a novice when it comes to verilog. I have been tasked with producing a frequency divider implemented in verilog from a...

For example, if you had a 100MHz clock to start from, and didn't want to use a PLL to create any of these other clocks, you could create an approximate 15MHz enable signal using a fractional divider. In this case, your code might look like: // The step is given by the desired ...

21.The apparatus of claim 20, further including:a second order delta-sigma modulator (DSM) to generate a DSM output based on the alpha fractional DTC code, a PLL integer, and a pseudo-random bit sequence (PRBS); anda multi-modulo divider (MMD) to generate the received PLL input based on...
In the Band Group Selector block610, the output signal from a high frequency local oscillator612travels though a frequency divider613(depending on the switch) in order to synthesise the centre frequencies, fC, of band groups1to5. Band groups6to10can be selected by enabling the 60 GHz up-co...
