A Co‐Designed Implicit‐Reset Path PFD and Current Mismatch Compensated CP Enabling Sub‐0.5% Mismatch and Dead Zone‐Free for Low‐Spur PLLs

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A co‐designed implicit‐reset phase‐frequency detector (PFD) and nonlinear amplifier‐assisted charge pump (CP) achieve dead zone‐free operation from 10 MHz to 4.7 GHz with < 0.5% current mismatch without calibration, enabling −80 dBc of reference spur and 0.50 ps of RMS jitter in a 180 nm of CMOS PLL.

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Unveiling Bubble Dynamics of Proton Exchange Membrane Water Electrolysis at Elevated Temperatures

open access: yesEcoEnergy, EarlyView.
This work directly visualizes bubble dynamics in a proton‐exchange membrane water electrolyzer operated at temperatures up to 120°C and pressures up to 100 bar. Elevated‐temperature operation beyond the atmospheric boiling point markedly reduces bubble coverage, leading to lower bubble‐related voltage losses and enhancing cell performance.
