Nonreciprocity in Microwave Optomechanical Circuits

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth

Nonreciprocal devices such as isolators and circulators are necessary to protect sensitive apparatus from unwanted noise. Recently, a variety of alternatives were proposed to replace ferrite-based commercial technologies, with the motivation to be integrat ...

Simple thermal noise estimation of OTA-based switched-capacitor filters

Christian Enz, Assim Boukhayma, François Krummenacher

This paper presents a new analytical method to simply estimate the integrated thermal noise in switched-capacitor filters (SCF). It is shown how the Bode theorem, which is theoretically valid only for continuous-time passive filters, can be extended to als ...

Recent trends in low-frequency noise reduction techniques for integrated circuits

Christian Enz, Assim Boukhayma

This paper presents the two main circuit techniques, namely autozeroing (AZ) and chopper stabilization (CS), that are used to reduce the 1/f noise and offset in amplifiers typically used in sensor electronics interfaces. After recalling their main properti ...

Low distortion switched-capacitor event-driven analog to digital converter

Alexandre Schmid, Yusuf Leblebici

An event-driven tracking analog to digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC non-linearity, reduces the swing and dynamic common-mode range requirement of the operational transcond ...

On-Chip Digital Background Calibration of Pipelined Analog-to-Digital Converters using Digital Assistance to support Nonlinear Residue Amplification

Thomas Liechti

This thesis describes a novel digital background calibration scheme for pipelined ADCs with nonlinear interstage gain. Errors caused by the nonlinear gains are corrected in real-time by adaptively post-processing the digital stage outputs. The goal of this ...
