Time-Domain ADPLL BPSK, QPSK, and 8PSK Demodulators

Journal of Electrical and Computer Engineering
Time-domain all-digital-phase-locked-loop phase-shift-keying (PSK) demodulators are proposed for BPSK, QPSK, and 8PSK signals. The demodulator architectures are highly suitable for low-voltage nanoscale CMOS techology.

FPGA Based Modelling of an ADPLL Network [PDF]

2019 16th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD), 2019
This paper introduces and compares the implementation of a number of FPGA based ADPLL network prototyping architectures. Networks are then created using three different ADPLL implementations and tests performed on each. Based on these test results, comparison is made to both the expected performance and role of each ADPLL design as a development tool.

Parallel PWMs based fully digital transmitter with wide carrier frequency range. [PDF]

ScientificWorldJournal, 2013
The carrier‐frequency (CF) and intermediate‐frequency (IF) pulse‐width modulators (PWMs) based on delay lines are proposed, where baseband signals are conveyed by both positions and pulse widths or densities of the carrier clock. By combining IF‐PWM and precorrected CF‐PWM, a fully digital transmitter with unit‐delay autocalibration is implemented in ...

An Interpolated Flying-Adder-Based Frequency Synthesizer

Journal of Electrical and Computer Engineering, 2011
This work presents an interpolated flying-adder- (FA-) based frequency synthesizer. The architecture of an interpolated FA, which uses an interpolated multiplexer (MUX) to replace the multiplexer in conventional flying adder, improves the cycle-to-cycle ...

Contributions to the analysis and design of an ADPLL [PDF]

2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006
In this paper, we propose two contributions to the simulation and design of an All-Digital Phase-Locked Loop (ADPLL) for RF applications. First, we extend the behavioral model we already proposed, in order to include detailed fractional aspects. Second, we propose a new adaptive algorithm that can be integrated in this ADPLL in order to lower its ...
