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 (

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

Prediction of GaAs metal–semiconductor field-effect transistor parameter spread

Технологія та конструювання в електронній апаратурі, 2006
It is shown that for Schottky-barrier field-effect transistors based on three-layer GaAs structures (film – buffer layer – substrate), the parameter spread caused by the nonuniform distribution of deep centers across the wafer can be characterized by a ...
