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.

Toward Long‐Term Reliable Human‐Machine Interaction: A Flexible, Breathable, and Self‐Powered Pressure Sensor System With Firefighting Validation

Advanced Science, EarlyView.
This work develops a breathable potentiometric self‐powered pressure sensor with good wearability, using a non‐woven fabric substrate and hydrogel electrolyte. The sensor is integrated into a five‐channel smart glove to acquire reliable hand motion signals, which are processed by a CNN for identity verification and smart vehicle control in human ...

A Second Harmonic Current Suppression Strategy Based on a Digital Band-Stop Filter With Center Frequency Tracking Grid Frequency

IEEE Access
In a single-phase grid-tie system, the presence of a second harmonic current (SHC) on the DC side reduces the conversion efficiency and lifetime of the DC source.

Wavelength‐Dependent Photobiomodulation Regulates Macrophage Polarization via Mitochondrial Dynamics and Metabolic Reprogramming

Advanced Science, EarlyView.
Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.

The Implementation and Analysis of an All-digital Phase-locked Loop

, 2012
[[abstract]]An all-digital phase-locked loop (ADPLL) circuit is presented. The feature of the ADPLL is that its resolution in the phase detector and digitally controlled oscillator (DCO) exactly matches the gate-delay time.

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 ...

Boosting Ferroelectricity: 2D and Polymer Ferroelectric Hybrids Enabling Ambipolar Nonvolatile MoS2 Memory Transistor

Advanced Science, EarlyView.
Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).
