These devices provide 6 dB of gain control range with integrated peak detector
on each channel for closed loop control.
The driver integrates the peak detector
and the temperature monitor.
The walk error correction technique had been proposed using the measured peak amplitude information by a peak detector
and a Gilbert cell .
CNFET-FCOA-Based Peak Detector
. As the name suggests, a peak detector
is a circuit which detects the peak value of applied input signal [41, 43] as shown in Figure 5(m).
This peak detector
sets a variable threshold that is dependent on the mean intensity of each individual image.
Therefore a peak detector
is used to capture these short pulses.
This information is utilized by the peak detector
to arrive at the peaks of QRS complex.
In order to generate the push-pull control voltage, the two peak voltages are generated using a peak detector
It is designed, simulated and fabricated using a 0.18om 1P6M CMOS technology.The fabricated current-mode AGC chip consists of a current peak detector
, a current subtractor, a circuit which consists of a square current generator and a current divider.
In the second step Blais and Rioux linear peak detector
(Blais & Rioux 1986) is used since it provides the best results for subpixel position estimation (Fisher & Nadiu 1996).
At the top of the list was battery life followed closely by peak detector
performance and overall size of the ASIC.
A peak detector
follows the response of IF signals such that the voltage at the detector output follows the peak value of the IF signal at all times.
