A novel low-voltage low-power wave digital filter bank for an intelligent noise reduction digital hearing instrument

We propose an acoustic noise suppression system embodying a novel low-voltage low-power multiplexed 16-channel lattice wave digital filter bank (LWDFB) for an intelligent digital hearing instrument. This system alleviates the intensity of computation problem and eliminates the delay problem of FFT-1FFT-based systems. To satisfy the tight constraints of low voltage, low power and a small IC area...

An Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)

this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...

An Intelligent Algorithm based Controller for Multiple Output DC-DC Converters with Voltage Mode Weighting Factor

Multiple output DC-DC converters are widely used in many applications such as aerospace, industrial and medical equipments. The purpose of this paper is to present an intelligent control system for the multiple output DC-DC converters. In order to perform this purpose, a double ended forward DC-DC converter with three output voltages (+5 V/ 50W, +15 V/ 45W and -15 V/ 15W) is considered and anal...

An ultra low-power low-voltage switched-comparator successive approximation analog to digital converter

A 9-bit ultra low-power successive approximation analogto-digital converter (SA-ADC), which is able to operate at very low supply voltage, is presented. The low power consumption is achieved by using new switched-comparator architecture. In the proposed architecture the comparator, which is one of the most power hungry blocks of the SA-ADC, is switched off after the decision-making interval as ...
