An RC oscillator using amorphous silicon thin film transistors was developed. The oscillation
frequency and its dependence on resistance and bias voltage were studied. The frequency …

A very simple and efficient scheme for jitter reduction is proposed for a carrier frequency
recovery loop using phase differential frequency estimation, which estimates the current …

We propose a new method to build a biphase sinusoidal generator which provides two
signals: v 1= V m sin (ω t) and v 2= V m sin (ω t+ φ)⁠, where V m⁠, ω⁠, and φ are digitally …

No intervalo de valores de frequência de poucos kHz até 1 MHz, nomeado às vezes como
região de dispersão?, as estruturas das células são o principal determinante da impedância …

This paper describes general overview of the DDC by explaining its individual blocks (NCO,
CFIR, PFIR, and CIC) and their implementation in MATLAB SIMULINK and XILINX system …

This paper describes a biphase sinusoidal generator which provides two signals: v ref= VM
sin (ω t) and v out= VM sin (ω t+ Δ Φ)⁠, where Δ Φ is in the range 0, π/2 or− π/2⁠, 0 and is …

Dans le cadre de ce travail, nous avons analysé les performances d'un récepteur GPS
numérique reprogrammable. Avec le développement de plus en plus rapide des systèmes …

Both the steady-state and transient performances of a carrier frequency recovery loop are
improved by simply overlapping the observation intervals for successive frequency offset …
