We report a high efficiency sub-6GHz wideband Envelope-Tracking Power Amplifier (ET-PA) including a soft-switching buck-converter and a wideband RF-PA, used in conjunction with a digital front end
In a next-generation digital cellular telephone transmitter, employing quadrature amplitude modulation, it is required that the post modulator amplifiers be amplitude linear so as to preserve the v
We report the use of a new, extremely efficient electron energy analyzer for recording high resolution electron spectra from multiphoton photoemission.
This paper describes a telephone receiver of the moving coil type which is particularly adaptable to the horn type of loud speaker and which represents a notable advance over similar devices at pre
This paper makes several contributions to the common IPC development. The first one is the shared memory self-healing circular buffer design.
This paper describes the design features and performance of a circuit pack to backplane multifiber optical connector capable of interconnecting up to 18 fibers through the backplane of an electroni
Small-scale vibration energy harvesters that respond efficiently at low frequencies are challenging to realise.
A 400-Gbps WDM-OFDM LR-PON over 60-km SMF is demonstrated with a 10G-class EAM and PIN.
Polarity discontinuities at atomically abrupt crystalline heterointerfaces can lead to nontrivial local atomic and electronic structure, due to the presence of dangling bonds and incomplete coordin
Here we have examined a model interface between two insulating perovskites, LaAlO3 and SrTiO3, controlling the termination layer at the interface on an atomic scale.
