Performance comparison of integrated fully-differential filterless class-D amplifiers with different feedback techniques
Analog Integrated Circuits and Signal Processing - Tập 76 - Trang 167-177 - 2013
Yuh-Shyan Hwang, Jian-Hong Shen, Jiann-Jong Chen, Ming-Ren Fan
Two integrated stereo fully differential filterless class-D amplifiers are presented in this paper. The object is to develop a modulation of a class-D audio amplifier with high power efficiency in this paper. The traditional H-bridge class-D audio amplifier has a shortcoming of large signal distortion which is worse than realized. However, the proposed circuit improves the drawback and provides hi... hiện toàn bộ
NANO-studio, the design environment of filter banks implemented in standard CMOS technology
Analog Integrated Circuits and Signal Processing - Tập 109 - Trang 323-333 - 2021
Andrzej Handkiewicz, Mariusz Naumowicz
The paper presents a method of optimizing frequency characteristics of filter banks in terms of their implementation in digital CMOS technologies in nanoscale. Usability of such filters is demonstrated by frequency-interleaved (FI) analog-to-digital converters (ADC). An analysis filter present in these converters was designed in switched-current technique. However, due to huge technological pitch ... hiện toàn bộ
Design of new practical phase shaping circuit using optimal pole–zero interlacing algorithm for fractional order PID controller
Analog Integrated Circuits and Signal Processing - Tập 91 - Trang 131-145 - 2017
Mohan V. Aware, Anjali S. Junghare, Swapnil W. Khubalkar, Ashwin Dhabale, Shantanu Das, Rutuja Dive
This paper presents the implementation of fractional order PID (FO-PID) controller using hardwired modules of constant phase element (CPE). A new approach of phase shaping by slope cancellation of asymptotic phase plots for zeros and poles within the given bandwidth is realized. Analog circuits, which exhibit analog fractional-order integrator and fractional-order differentiator, are used for buil... hiện toàn bộ
Energy-efficient and two-step structure switching scheme based on reference-free for SAR ADC
Analog Integrated Circuits and Signal Processing - Tập 99 Số 1 - Trang 209-218 - 2019

Analysis and Compensation of Log-Domain Biquadratic Filter Response Deviations due to Transistor Nonidealities
Analog Integrated Circuits and Signal Processing - Tập 22 - Trang 147-162 - 2000
Vincent W. Leung, Gordon W. Roberts
A translinear log-domain integrator, the powerhouse of log-domain filtering techniques, is analyzed to determine its deviations due to major time-invariant bipolar transistor imperfections, such as parasitic emitter and base resistances, finite beta, Early effect, and area mismatches. The results are used to predict the transfer function deviations of biquad filters, for both lowpass and bandpass ... hiện toàn bộ

GigaHertz MUX-DEMUX Chip with HF BIST
Analog Integrated Circuits and Signal Processing - Tập 12 - Trang 29-48 - 1997
Lars Hellberg, Owe Thessén, Hannu Tenhunen, José-Maria Gobbi
Full functional test at speed, in-situ is an ideal choice for use for detection of errors in circuit behaviour for high speed broadband communication circuits and to avoid test set-up disturbances on high frequency signals. This article presents a novel technique to solve the high frequency test of Gbit/s data rate Time-Division Multiplexer/Demultiplexer circuits. This in-situ test technique is ba... hiện toàn bộ
Design and Analysis of a CMOS Switched-Current Sigma-Delta Modulator Using Multi Level Simulations
Analog Integrated Circuits and Signal Processing - Tập 15 - Trang 153-168 - 1998
Ping Zhu, Hannu Tenhunen
This paper presents the design of a 3.3V CMOS switched-current (SI) second-order sigma-delta modulator for A/D converters intended for radio front-end applications. The effects of non-ideal behaviours of the building blocks on the total performance of a SI double-integrator sigma-delta modulator (DISDM) were analysed and simulated by means of multi level (SpectreHDL-level, transistor-level) and mi... hiện toàn bộ
A Transformer-neutralized 0.6 V V DD 17–29 GHz LNA and its application to an RF front-end
Analog Integrated Circuits and Signal Processing - Tập 83 - Trang 173-186 - 2015
Sandipan Kundu, Jeyanandh Paramesh
A low-noise (LNA) amplifier that combines transformer-neutralization with bandwidth enhancement is introduced to enable a compact design capable of operating from a widely scalable supply voltage. A supply-voltage scalable 17–29 GHz ultra-wideband (UWB) multi-stage LNA prototype employing a single transistor between V DD and ground in all stages, and using the aforementioned techniques, is fabrica... hiện toàn bộ
