The paper describes a simple high-Q insensitive active band-pass filter having relatively few passive components and active elements with low closed-loop gains, using positive feedback Q enhancement scheme. The proposed filter has minimum dependence on the bandwidth of the operational amplifiers and ...
Using MathCAD to draw the error isogram of Voltage-controlled VoltageSource(VCVS) 2nd-order high-pass filter's parametric equation,after analysis and research,the paper puts forward an optimized design scheme: firstly,selecting two capacitances C1 and C2,making C1= C2;and then calculating the val...

As the required filter function is rather complex, manufacturable devices can only approximate the ideal filter function for a perfectly flat gain. In addition, the shape of the active fiber gain spectrum and the shape of the filter loss spectrum may exhibit different temperature dependences. As a...
This low noise amplifier utilizes improved techniques on current-reuse topology and high-pass input matching network to achieve high gain and low noise. The LNA presents a maximum power gain of 14.6 dB at 6 GHz. The simulated minimum noise figure (NF) is 2.5 dB with less than -12.6 dB ...
It is easy to create a filter that allows the amplified signal at 915 MHz to pass through while rejecting signals at twice that frequency, and at very low frequencies. What about third-order distortion? Here the situation is both more complex and less amenable to correction. The mathematics ...
-20 dB power and between of 1565-1610 nm L band signals are applied to this four configurations and reached to highest gain in double-pass configuration, lowest noise figure in two-stage amplifier and two-stage with gain flattening filter configurations, and lowest gain ripple in two-stages ...
In five patients the neural activity was recorded with a 128 channels clinical video-EEG recording system (SD LTM 64 BS, Micromed® S.p.A., Italy), sampling at 1024 Hz with a band-pass filter of 0.15–250 Hz. In the other eight patients, the recording was implemented with a ...
or ac-bias – AC-biasing is allowed with the use of external pull-up resistors to the positive power supply • Sixth-order, low-pass filter for DAC reconstruction or ADC image rejection: – 9.5 MHz for NTSC, PAL, SECAM, and composite video (CVBS) signals – 72 MHz for 1080p60 Y'...
A 40MHz low-pass filter is provided as part of the converter interface to both limit broadband noise and reduce harmonics as the signal frequency exceeds 15MHz. The noninverting input bias voltage is referenced to the midpoint of the ADC signal range by dividing off the top and bottom of ...
