Transformation of different types of switched-capacitor (SC) biquad filter stages based on FleischerLaker biquad SC structure in order to support oscillation based testing (OBT) have been proposed. The derived solutions are based on the generic Fleischer-Laker biquad SC structure assuming ideal characteristics of the employed components. In this paper, we explore the operation of the proposed O...
This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (floating gate and switched capacitor), and conductance/current.
The aim of this research is to present a simple online condition monitoring system to predict failure of the aluminum electrolytic capacitors used in the output LC filter of the switched mode DC–DC buck converters. Equivalent Series Resistance (ESR) is the best indicator of the failure of the aluminium electrolytic capacitors. The main idea of the proposed method is to monitor the ESR value and...
Abstract: Analog sampling systems based on switched capacitor techniques offer performance superior to that of flash A/D converters with respect to cost, density, dynamic range, sampling speed, and power consumption. This paper proposes a 500 MHz switched capacitor analog waveform sampling circuit for the camera electronics of the Cherenkov telescope. An experimental 4 channel analog memory wit...
The effect of MOSFET gate-oxide reliability on MOS switch with bootstrapped technique is investigated with the switched-capacitor circuit in a 130-nm CMOS process. The sample-and-hold amplifier with the openloop configuration is used to verify the impact of MOS switch gate-oxide reliability on the switched-capacitor circuit. After overstress on the MOS switch of sampleand-hold amplifier, the ci...
A 4.6 W/mm2 Power Density 86% Efficiency On-Chip Switched Capacitor DC-DC Converter in 32nm SOI CMOS
The future trends in microprocessor supply current requirements represent a bottleneck for next generation highperformance microprocessors since the number of supply pins will constitute an increasingly larger fraction of the total number of package pins available. This leaves few pins available for signaling. On-chip power conversion is a means to overcome this limitation by increasing the inp...
A behavioral model of a second order switchedcapacitor Sigma-Delta modulator is presented. The purpose of this work is the presentation of a behavioral model of a second order switched capacitor ΣΔ modulator considering (Error due to Clock Jitter, Thermal noise Amplifier Noise, Amplifier Slew-Rate, Non linearity of amplifiers, Gain error, Charge Injection, Clock Feedthrough, and Nonlinear on-re...
Abstrac tThis paper presents a procedure for the power-optimal design of high-resolution low-bandwidth switched-capacitor (SC) ∆Σ modulators (∆ΣMs). The most power efficient ΔΣ architecture is identified among single-loop switched-capacitor (SC) feedback (FB) and feed-forward (FF) topologies with different loop order N, oversampling ratio OSR, and quantizer resolution B. Based on the results ob...
