Ab&ructWith the growing demand for high-speed transmission of digital data, there is a challenge for utilizing the existing copper plant as the transmission medium, especially for shorthop links. This medium offers a lower cost to a fiber medium, but requires more sophisticated electronics to account for electromagnetic emissions, cross-talk, and cable loss. These include pulse shaping filters,...

Masyarakat Palembang telah lama sekali mempergunakan sungai musi sebagai sarana tempat mandi, mencuci dan bisa diolah menjadi air minum yang higienis atau terhindar dari bakteri, oleh karena itu untuk perlu menjaga agar di tetap terjaga ekosistemnya, maka disini dijaga kelestarian musi. itulah peneliti akan mencoba memonitoring sungai. Penerapan antena biquad perangkat sistem pada dasarnya adal...

Most biopotential readout front-ends rely on the g m- C lowpass filter (LPF) for forefront signal conditioning. A small g m realizes a large time constant ( τ = C / g m) suitable for ultra-low-cutoff filtering, saving both power and area. Yet, the noise and linearity can be compromised, given that each g m cell can involve one or several noisy and nonlinear V- I conversions originated from the ...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

The paper presents a fully differential log-domain low-pass second order filter. The topology was derived, using a LINELIN transformation, from a standard state-variable biquad. The filter allow for orthogonal parameter tuning. Its low-frequency gain (H0), natural pulsation (ω0) and quality factor (Q) can be tuned continuously by varying only DC bias currents. The filter was implemented in a ge...
