High-resolution FPGA-pulse width modulation applied to PFC 2 MHz converter using eGaN field effect transistor

The Journal of Engineering, 2019
This study proposes an implementation based on a low-cost field-programmable gate array (FPGA) of a high-resolution pulse width modulation applied on a single-phase power factor correction (PFC) converter operating with 2 MHz switch frequency.

Theory of a field effect transistor based on semiconductor nanocrystal array [PDF]

Phys. Rev. B 89, 235303 (2014), 2014
We study the surface conductivity of a field-effect transistor (FET) made of periodic array of spherical semiconductor nanocrystals (NCs). We show that electrons introduced to NCs by the gate voltage occupy one or two layers of the array. Computer simulations and analytical theory are used to study the array screening and corresponding evolution of ...

Multi-exposure laser speckle contrast imaging using a high frame rate CMOS sensor with a field programmable gate array.

Optics Letters, 2015
A system has been developed in which multi-exposure laser speckle contrast imaging (LSCI) is implemented using a high frame rate CMOS imaging sensor chip. Processing is performed using a field programmable gate array (FPGA).

Rydberg-blockade controlled-not gate and entanglement in a two-dimensional array of neutral-atom qubits [PDF]

, 2015
We present experimental results on two-qubit Rydberg blockade quantum gates and entanglement in a two-dimensional qubit array. Without post selection against atom loss we achieve a Bell state fidelity of $0.73\pm 0.05$, the highest value reported to date.
