A dual MOSFET from ROHM offers high power density, low losses, and bidirectional protection for smartphone batteries.

SOP Advance(E) package enables lower loss and higher efficiency for industrial equipment, data centres, and base stations ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible.

In high-efficiency Class E amplifiers matching circuits are commonly used to transform usually constant load resistance to nominal or off-nominal resistance of the amplifier to ensure its ZVS ...

This letter proposes a Sub-GHz digital polar power amplifier circuit, which is intrinsically linear and power efficient. The architecture is based on a 1-bit delta–sigma modulator (DSM) to achieve ...
