A New Architecture of Digital Frequency Synthesizer

نویسنده

چکیده

Frequency synthesis has many applications in today’s commercial electronic and telecommunications system design. Some techniques exist which can be used to generate a frequency that is an integer or fractional multiple of a reference frequency. This paper describes architecture a new pure digital frequency synthesizer based on generators, counters and a register. The technique described here is much simpler then other method. Presented synthesizer is the most suitable for the design of VLSI architectures or for programmable Large Scale Integration. On the other hand, this synthesizer has a disadvantage in low output frequency.

Design and Simulation of a Modified 32-bit ROM-based Direct Digital Frequency Synthesizer on FPGA

This paper presents a modified 32-bit ROM-based Direct Digital Frequency Synthesizer (DDFS). Maximum output frequency of the DDFS is limited by the structure of the accumulator used in the DDFS architecture. The hierarchical pipeline accumulator (HPA) presented in this paper has less propagation delay time rather than the conventional structures. Therefore, it results in both higher maximum ope...

An all - digital - - frequency discriminator of arbitrary order

In this paper, we propose an all-digital frequency output of the synthesizer. High reference frequency (REF) is synthesizer architecture, based on an all-digital XA-frequency used to push the spurs far from the carrier. The need for high discriminator. The new all-digital synthesizer is compared to sampling frequency, in addition to the resolution being previously published work. The architectu...

Digital High Order Multiplier-free Delta Sigma Modulator for Multistandard Fractional-N Frequency Synthesizer

This paper proposes a new stable design strategy for 1bit high order digital ∆Σ modulator for multistandard fractionalN frequency synthesizer. The proposed digital ∆Σ modulator presents simplicity, low power consumption and controls a dualmodulus divider instead of multi-modulus one as in existing ∆Σ fractional-N frequency synthesizer. Simulation results illustrate the ∆Σ modulator good perform...
