Noise figure of a balanced amplifier

, 2018
Noise figure expression of a balanced amplifier built with lossy divider and combiner and two imperfectly noise-matched component amplifiers is derived analytically using the method of noise waves in terms of the noise parameters of the amplifiers.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

A 120 GHz Hybrid Low Noise Amplifier in 40 nm CMOS

IEEE Access
In this paper, we present a 6-stage 120 GHz hybrid low noise amplifier (LNA) for sub-THz radar systems. To enhance the noise figure (NF) and gain performance of the LNA, we propose a hybrid architecture that utilizes a combination of 2-stage single-ended

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,
