Polyphase Nonlinear Equalization of Time-Interleaved Analog-to-Digital Converters
TLDR
We develop a polyphase NonLinear EQualizer (pNLEQ) which is capable of simultaneously mitigating distortion generated by both the on-chip circuitry and mismatches due to time interleaving. Expand

High-speed mid-infrared hyperspectral imaging using quantum cascade lasers
We report on a standoff chemical detection system using widely tunable external-cavity quantum cascade lasers (ECQCLs) to illuminate target surfaces in the mid infrared (λ = 7.4 – 10.5 μm).Expand

A New Approach to Achieving High-Performance Power Amplifier Linearization
TLDR
Digital baseband predistortion (DBP) is not particularly well suited to linearizing wideband power amplifiers (PAs); this is due to the exorbitant price paid in computational complexity. Expand
