Low Power Ultra‐Wideband Low‐Noise Amplifier for UWB Receiver

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
This paper presents a 4–13 GHz UWB LNA designed in a 65 nm CMOS process, adopting gate inductor‐assisted impedance matching and current reuse feed‐forward noise cancellation. The LNA achieves 16.9 dB gain, 4.3 dB minimum NF, and only 9.4 mW power consumption from a 1 V supply.

Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits

open access: yesLaser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...
