Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Layer‐Dependent Antiferromagnetic Chern and Axion Insulating States in UOTe
Advanced Science, EarlyView.Layer‐dependent topological phases are identified in the van der Waals antiferromagnet UOTe. Ab initio calculations reveal bilayer UOTe as a rare example of high‐temperature antiferromagnetic Chern insulator with quantized Hall conductivity and near‐zero net magnetization, while odd‐layer films exhibit axion‐insulator‐like behavior with quantized spin ...

A Supramolecular Ferroelectric With Two Sublattices and Polarization Dependent Conductivity
Advanced Science, EarlyView.Ferroelectric behavior in a supramolecular material with two, independently switchable, sublattices is demonstrated. The sublattices can be associated with the two dipolar groups in the compound. Moreover, the polarization is found to couple to the charge transport in the material, giving rise to a switchable, directional conductivity.

Integrated switched-capacitor FDNR filter
IEEE Journal of Solid-State Circuits, 1983A switched-capacitor filter using a frequency-dependent negative resistance (FDNR) is described. FDNR filters closely simulate passive LC filters, thereby retaining passband stability and design simplicity. The filter has been implemented in LSI and designed to perform the transmit/receive filtering for PCM codecs.

Fully Integrated Switched-Capacitor Power Converters
2023Since both switches and capacitors shrink with advanced integrated circuit processes, fully integrated switched-capacitor (SC) power converters become a popular solution for on-chip point-of-load power delivery. This chapter covers the topology design, multiphase and multistate operations, loss analyses, and efficiency optimization considerations for a

Offset-compensated switched-capacitor integrators
IEEE International Symposium on Circuits and Systems, 2002The performance of several switched-capacitor (SC) integrators is compared, and a description representation is introduced. Offset-compensated circuits which reduce the capacitance spread in very large time-constant SC integrators are presented. The theoretical equations are derived for all SC circuits and are then confirmed by simulations. >

Fully Integrated Switched-Capacitor Fundamentals
2020As discussed in Chap. 1, there is a clear drive towards monolithic power conversion, and SC converters in particular are an excellent candidate for full integration. Before proceeding to more advanced topics, this chapter will go over the fundamental principles behind SC DC–DC converters.
