Electrohydrodynamically printed solid-state Photo-electro protein micro-capacitors …
EIS was used to investigate the effect of the width of the printed protein line on electrochemical performance. Protein lines of 283 µm, 318 µm and 427 µm in width were created by varying the printing speed. EIS data on the resulting MCs were fitted by a Randles equivalent circuit (Figure S5 in Supplementary information) consisting of an …

It is found that the excessive high-frequency ripple current typically flows through electrolytic capacitors (E-caps). A dedicated transformer-based sensor is then designed, …
A novel high‐voltage solid‐state switch based on the SiC MOSFET series and its overcurrent protection
Due to compactness, high frequency, and controllability of all-solid-state switches [], there is a growing trend to replace conventional switching devices with all-solid-state switches [15, 16]. In recent years, with the development of silicon-based devices, silicon materials have developed to the limit of their physical properties.

An improved frequency compensation technique for CMOS …
The commonly used two-stage CMOS operational amplifier suffers from two basic performance limitations due to the RC compensation network around the second gain stage. First, it provides stable operation for only a limited range of capacitive loads, and second, the power supply rejection shows severe degradation above the open-loop pole …
Solid-state electric double layer capacitors for ac line-filtering
1. Introduction In modern electronics, removing voltage fluctuations (rectification ripple) is necessary when converting alternating current (ac) to direct current (DC). Generally a capacitor is used for this purpose. The present solution for 120 Hz power filtering (double the value of the 60 Hz standard ac line frequency in the United States) is …
Biquad alternatives for high-frequency switched-capacitor filters
Biquad sections are the basic building block of practical switched-capacitor (SC) filters. The authors focus on the amenability of various biquad options for high-frequency operation. A comparison on the basis of analysis and a recent nonideal SC network simulation tool are confirmed by results from a VLSI 1.25-/spl mu/m CMOS test chip. A differencing-input SC …

This article proposes a novel submodule capacitor voltage balancing control for multiport modular multilevel converter (MMC)-based solid-state transformers.
They offer a higher capacitance per unit volume compared to solid-state capacitors, which means they can store more energy. For example, an electrolytic capacitor can store up to 100,000 microfarads, while a solid-state capacitor is limited to about 1 microfarad.
