Phase - locked Loop Digital FM Receiver for Wireless

We investigate a non-coherent detection technique based on phase-locked loop (PLL) for wireless communication applications, with an emphasis on Digital Enhanced Cordless Telephone (DECT) system. Performance of the PLL receiver in additive white Gaussian noise (AWGN)'and interference-limited environments is simulated and compared to that of the "traditional" non-coherent receivers: limiter-discr...

A Frequency Synthesis of All Digital Phase Locked Loop

All Digital Phase locked loops (ADPLL) plays a major role in System on Chips (SoC). Many EDA tools are used to design such complicated ADPLLs. It operates on two modes such as frequency acquisition mode and phase acquisition mode. Frequency acquisition mode is faster compared to Phase acquisition, hence frequency synthesis is performed. The CMOS technology is used to design such a complex desig...

Fuzzy logic for digital phase-locked loop filter design

The problem of robust phase-locked loop design has attracted attention for many years, particularly since the advent of the global positioning system. This paper proposes and demonstrates the use of a fuzzy PLL to estimate the time-varying phase of a sinusoidal signal. It is shown via simulation results that fuzzy PLL's offer performance comparable to analytically derived PLL's (e.g. Kalman fil...

All-Digital Phase Locked Loop (ADPLL) -A Review

--The All-Digital Phase-Locked Loop (ADPLL) is digital electronic circuit that are used in modern electronic communication systems like frequency synthesizer, modulator/demodulator etc. This paper presents a review of various ADPLL techniques. The range of input frequency of ADPLL is 40 to 98 MHz; the output frequency may be up to 2.92 to 4 GHz range. The components of ADPLL such as phase detec...
