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

Balanced-to-Balanced Microstrip Diplexer Based on Magnetically Coupled Resonators
IEEE Access, 2018 Two balanced-to-balanced planar diplexers based on magnetically coupled microstrip resonators are proposed in this paper. For the first prototype, each channel/differential-output is composed of a second order single-band balanced bandpass filter based ...

Finite common-mode rejection in fully differential operational amplifiers
Electronics Letters, 2006 A nonlinear mechanism which affects common-mode rejection (CMR) of fully differential integrated operational amplifiers (opamps) is highlighted and analysed by computer simulations. In particular, it is shown how the finite CMR of fully differential opamp circuits under practical operating conditions is mainly related to such a mechanism rather than to

FEBS Open Bio, EarlyView.Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Low-voltage balanced transconductorwith high input common-mode rejection
Electronics Letters, 1994 A balanced transconductor architecture with a high input common-mode (CM) rejection and capable of operating with low supply voltage is proposed. The novel structure is based on a feedforward cancellation of the input CM signal, implemented with an additional transconductor sensitive only to CM signals.
