A 192 nW 0.02 Hz High Pass Corner Acoustic Analog Front-End with Automatic Saturation Detection and Recovery

Kyojin Choo

We present an acoustic analog front-end with a 100TΩ feedback resistance that is robust to PT variation (1.8× deviation across –40 to 80°C and 0.035× σ/µ across 16 measured samples) and achieves a 3.3× reduction in input referred noise (IRN). It eliminates ...

Architectural Modeling of a Single-Sideband Wireline Serial Data Transceiver for Multi-Drop I/O

Yusuf Leblebici, Gain Kim

This paper presents a wireline serial data transceiver (TRX) architecture employing a concept of single-sideband (SSB) modulation to transmit data over a multi-drop (MD) electrical link with deep notches. The proposed TRX utilizes channel notch as a filter ...

Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin, Pavle Belanovic

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...
