Various basic, efficient and cheap techniques are used for the purpose of life forecast and failure detection of aluminum electrolytic capacitors which are utilized as a part of many power electronic converters. The main idea of these techniques is to calculate the values of Equivalent Series Resistance (ESR) and Capacitance (C). Observing the ESR values, valuation of changes in voltage and cur...

This paper proposes 128x100 array fingerprint sensor with the modified parasitic insensitive switched capacitor integrator. The modified parasitic insensitive switched capacitor integrator includes four switches to eliminate parasitic capacitance and transfer a generated charge. The proposed circuit also frees from the influence of skin resistivity, because the effect of the voltage drop throug...

A two stage sub-μW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and Local Field Potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices; however, in Switched Capacitor (SC) ci...

To use fewer components to construct a multilevel inverter (MLI) with more levels and high quality of the output voltage, hybrid MLI is developed by combining double-mode switched-capacitor (SC) unit T-type fed flying capacitors (FCs). The SC used boost amplitude voltage twice dc input while responsible for increasing number levels. A total ten transistors, four capacitors, two diodes are gener...

This paper presents a systematic methodology for producing reconfigurable ∆Σ modulator topologies with optimized flexibility in meeting variable performance specifications. To increase their flexibility, topologies are optimized for performance attributes pertaining to ranges of values rather than being single values. Topologies are implemented on switched-capacitor reconfigurable mixed-signal ...

Asymmetric multilevel inverters generate high-quality output voltage using the same number of components as symmetric inverters. The main drawback these topologies is that they require many DC sources, and power switches must endure high stress. In this paper, a switched-capacitor sub-module inverter topology proposed to reduce sources stress on asymmetric can 15 levels by two supplies capacito...
