Subthreshold Time‐Mode All‐Digital DLL With Built‐In Linearization

International Journal of Circuit Theory and Applications, EarlyView.
This paper presents a subthreshold time‐mode all‐digital delay‐locked loop (DLL) for low‐frequency clock generation. The large and tunable delay of the DLL is obtained using a static inverter delay line whose supply voltage is in the vicinity of 100 mV and adjustable by varying supply voltage. Phase error is processed by a time‐mode proportional block (

Parallel Multi‐Operand Addition Using CPA‐Trees and Carry‐Select Adders

International Journal of Circuit Theory and Applications, EarlyView.
A balanced parallel CPA‐tree architecture with CSLA reduces the critical‐path delay of multi‐operand addition while preserving structural regularity. ASIC results demonstrate delay reductions of up to 34% with low area overhead, providing an efficient and scalable solution for high‐performance arithmetic.

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

International 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

Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.
