A Survey of Filter Bank A/d Converters
نویسندگان
چکیده
Hybrid filter bank analog-to-digital converters (ADCs) have been proposed as a candidate for high-speed, high-resolution analog-to-digital conversion. It is a generalization from time-interleaved ADCs, but it has the advantage that the mismatch errors inherent in parallel converters are attenuated by the filters. This paper gives an overview of hybrid filter bank ADC analysis and design. Further some performance and implementation aspects are discussed.

Digital compensation scheme for coefficient errors of complex filter bank parallel A/D converter in low-IF receivers
In this paper, a digital compensation scheme for coefficient errors of a complex filter bank parallel A/D converter in low-IF receivers is presented. The complex filter bank is employed to suppress DC offset and image signals in the lowIF receivers and relax the requirements on the conversion rate and resolution of A/D converters. The proposed compensation scheme regenerates interference due to...
متن کاملDesign of Reconfigurable Digital Filter Bank for Hearing Aid
A hearing aid is an electroacoustic device for improving the hearing ability of hearing impaired. It should be designed such that it is able to adjust the magnitude response of arbitrary input frequencies, have low power consumption for reasonable battery life, output should be provided with a low delay and the overall structure should be small in size. In a simple hearing aid gain is applied t...
متن کاملModeling of time-interleavedADCswith nonlinear hybrid filter banks
In this paper, we model time-interleaved analog-to-digital converters (TIADCs) with nonlinear hybrid filter banks (NHFBs), which greatly unifies and simplifies the analysis of TIADCs. The input/output relation of such a nonlinear hybrid filter bank can be used to describe combined offset, gain, aperture delay, input behavior, and nonlinearity mismatches and is therefore an extendable starting p...
متن کاملDesign of a Digital Voltage Controller in Single-Phase Grid-Connected Renewable Converters
Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...
متن کاملAn Ultra Low-power Programmable DSP System for Hearing Aids and Other Audio Applications
This paper describes an application specific signal processor (ASSP) designed for miniature, ultra low-power, audio signal processing applications. The ASSP includes a high-fidelity weighted overlap-add (WOLA) filterbank, a 16-bit DSP core, two 14-bit A/D converters, a 14-bit D/A converter and a flexible set of peripherals. This design excels in applications that require efficient frequency-dom...
