Double-Layer E-Structure Equalization Circuit for Series Connected Battery Strings

Energies, 2019
In order to eliminate the voltage imbalance among battery cells when they are connected in series, the paper proposes a double-layer E-structure (DLE) equalizer based on bidirectional buck−boost converters, which has the advantage of quick ...

A Novel Inductorless Design Technique for Linear Equalization in Optical Receivers

Journal of Low Power Electronics and Applications, 2022
To mitigate the trade-off between gain and bandwidth of CMOS multistage amplifiers, a receiver front-end (FE) that employs a high-gain narrowband transimpedance amplifier (TIA) followed by an equalizing main amplifier (EMA) is proposed.
