Bandwidth Enhancement for Transimpedance Amplifiers [PDF]

IEEE Journal of Solid-State Circuits, 2004
A technique for bandwidth enhancement of a given amplifier is presented. Adding several interstage passive matching networks enables the control of transfer function and frequency response behavior. Parasitic capacitances of cascaded gain stages are isolated from each other and absorbed into passive networks.

Enhanced Bandwidth Efficiency of the Golden Code

2021 IEEE AFRICON, 2021
The conventional Golden code consists of two pairs of Golden codewords, each being a combination of two input symbols. This paper proposes an enhanced bandwidth-efficient scheme for the Golden code (EBE-GC) based on quadrature amplitude modulation (QAM). We then derive the average bit error probability for the EBE-GC scheme.

Bandwidth Enhancement of an Implantable Antenna

IEEE Antennas and Wireless Propagation Letters, 2015
An antenna with bandwidth enhancement is proposed for ingestible capsule systems at the Medical Device Radiocommunications Service (MedRadio, 401-406 MHz) band. The antenna is first designed and optimized in planar form on Rogers 3010 to validate the feasibility of the wideband performance.

Bandwidth extension for speech enhancement

CCECE 2010, 2010
In real-world wideband noisy recordings of speech, the Signal-to-Noise ratios in the lower half spectra are typically higher than those observed in their upper half counterparts, due to the average frequency distribution of the speech energy. Speech enhancement algorithms therefore struggle to recover damaged high frequency components, thereby ...

Design of Compact Filtennas with Enhanced Bandwidth

2018 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2018
Two compact, wideband filtennas are simulated and then measured. For the purpose of extending impedance bandwidth, the designs are introduced by organically uniting a monopole with a band-pass filter, and then regulating their mutual coupling. This method is adopted by incorporating filtering elements into antennas with near-field resonant parasitic ...
