High-Bandwidth Isolated Voltage Measurements With Very High Common Mode Rejection Ratio for WBG Power Converters

open access: yesIEEE Open Journal of Power Electronics, 2022
Galvanically isolated voltage measurements are becoming increasingly important for the characterization of converter systems with fast switching Wide-Bandgap (WBG) semiconductors. A very high Common Mode Rejection Ratio (CMRR) $> 80$dB for frequencies

Common mode electronic noise in differential circuits [PDF]

open access: yesMeasurement: Journal of the International Measurement Confederation, 2019
Differential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise.

Float solenoid balun for MRI. [PDF]

open access: yesNMR Biomed
This paper introduces the innovative float solenoid balun, based on the renowned solenoid cable trap, and conducts a comparative analysis with the widely used float bazooka balun. Abstract Baluns are crucial in MRI RF coils, essential for minimizing common‐mode currents, maintaining signal‐to‐noise ratio, and ensuring patient safety.

Reproducible and highly miniaturized bazooka RF Balun using a printed capacitor. [PDF]

open access: yesMagn Reson Med
Abstract Purpose There is currently a strong trend in developing RF coils that are high‐density, lightweight, and highly flexible. In addition to the resonator structure of the RF coil itself, the balun or cable trap circuit serves as another essential element in the functionality and sensitivity of RF coils.

A CMRR enhancement circuit by employing auxiliary buffer of capacitively coupled instrumentation amplifier for neural signal recording

open access: yesElectronics Letters, 2021
Here, a common‐mode rejection ratio (CMRR) enhancement circuit is proposed by employing an auxiliary buffer (AB) to the pseudo resistors of the capacitively coupled instrumentation amplifier (CCIA).

A Novel Differential to Single-Ended Converter for Ultra-Low-Voltage Inverter-Based OTAs

open access: yesIEEE Access, 2022
For the design of inverter-based OTAs with differential input and single-ended output, the differential to single-ended (D2S) converter is a key building block. In fact, the performance of the D2S strongly affects the overall common-mode rejection ratio (

Multimode interference filter to solve degradation on coupler common-mode rejection [PDF]

open access: yes, 1998
After quantifying degradation of a common mode rejection ratio (CMRR) 3dB-coupler due to excitation of TE01 mode, a novel compact circuit including multimode interference (MMI) coupler+bend+MMI+filter (CBF) is proposed.

A 0.3 V, Rail-to-Rail, Ultralow-Power, Non-Tailed, Body-Driven, Sub-Threshold Amplifier

open access: yesApplied Sciences, 2021
A novel, inverter-based, fully differential, body-driven, rail-to-rail, input stage topology is proposed in this paper. The input stage exploits a replica bias control loop to set the common mode current and a common mode feed-forward strategy to set its
