There has been a long-standing interest in controlling and instrumenting the human body. Whether to restore lost function with neural prosthetics, monitor blood glucose levels, or augment human capabilities, there are countless opportunities for sensors inside ( e.g., ingestible, injectable, and implantable) and outside ( e.g., wearable) the...

Small charge detection is used for a wide range of applications: advanced industrial process control, experimental physics and space instruments, and material testing and medical imaging. These applications give rise to the development of a wide variety of charge-sensitive readout integrated circuits (ROICs). The trend in the state-of-the-art...

Receivers for millimeter-wave (mm-wave) 5G, with the ability to detect a low-power desired signal, in the vicinity of large power blockers, require highly linear circuitry with a large power consumption. Suppressing the out-of-band blockers reduces this power consumption. N-path filters (NPFs) have recently been used to reject interferers in...

As electromagnetic waves cannot propagate sufficiently far in water, underwater communication is mainly performed using either acoustics or optics. However, none of these technologies have been proven to be completely effective in every situation. Therefore, research in new underwater communication systems can still bring large benefits to a...

This article presents the theory and implementation of a quadrature and differential RF front-end receiver. Combining balun, low-noise amplifier (LNA), mixer, and oscillator in a single stage, the proposed circuit, named the Blixator, is well suited for low-power applications. The baseband's transimpedance amplifier (TIA) also shares part of...

This article presents the experimentally characterized performance of a low noise and wideband sensor readout integrated circuit (ROIC). The ROIC is designed to detect small amounts of charge generated by a silicon p-i-n detector as a result of particle detection, with very high time resolution and limited power consumption. The architecture...

This letter presents a convenient approach based on the two-port kQ-product theory to analyze the influence of interwinding capacitive coupling on the efficiency of the transformer. It is demonstrated that a transformer with proper size can benefit from the interwinding capacitive coupling to maximize its efficiency at a desired frequency....

The landing gear system is the dominant airframe noise source for most modern commercial aircraft during approach. This manuscript reports the results from the ALLEGRA (Advanced Low Noise Landing (Main and Nose) Gear for Regional Aircraft) project. This project assessed the performance of several highly realistic low–noise technologies (LNTs)...

The purpose of this thesis is to evaluate a top-level topology for ultra-accurate power supplies. Chapter 3 shows that precision power supplies exist, but these are expensive and not stable on the long term. The correction scheme proposed in chapter 2 brings the accuracy of the best metrology systems to a high efficiency, low-noise power sup-ply...

This report describes the design of different amplifiers that are part of an FM transceiver. This is part of a larger project, which has the objective to design a complete FM transceiver from discrete components only, meaning that IC technology is not considered. <br/>The circuits designed are two baseband amplifiers, an intermediate frequency...

The SPICA-SAFARI instrument requires extremely sensitive transition edge sensor (TES) arrays with a noise equivalent power of 2×10-19W/Hz and a readout system with an output noise that is dominated by the detector noise. It is essential to ensure the frequency domain multiplexing (FDM) readout system in SAFARI meets the noise requirement. The...

This work presents a low-noise amplifier (LNA) for ultrasound imaging with built-in continuous time-gain compensation (TGC), which compensates for the time-dependent attenuation of the received echo signal and thus significantly reduces its dynamic range (DR). The proposed design combines the LNA and TGC functions in a single variable-gain...
