peak detector

peak detector

[′pēk di‚tek·tər]
(electronics)
A detector whose output voltage approximates the true peak value of an applied signal; the detector tracks the signal in its sample mode and preserves the highest input signal in its hold mode.

The driver integrates the peak detector and the temperature monitor.
Therefore a peak detector is used to capture these short pulses.
In AGC amplifier design, another important circuit is the peak detector, which will be used for generating the control voltage and then control the gain of whole circuit [17].
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.
1mm and integrates high frequency chokes and DC blocks for RF inputs and outputs and individual peak detector for each channel.
It allows the receiver to scan with the fast peak detector, and when the reading approaches a threshold such as a user-selected limit or limit with offset, it switches to the quasi-peak detector, and re-sweeps until the levels remain within the threshold.
The PMM 9010 also features the Smart Detector setting providing fast scanning using only the peak detector, which speeds up the click test and saves considerable time when compared with rescanning, especially for equipment under test that is only operated for short periods of time.
An optional Quasi Peak detector with three extra resolution bandwidth filters conforms to the recommendations for RF emissions measurements in accordance with the latest stringent EMC specifications instituted in Europe and North America.
In AGC mode the 1348TA/1349TA gain is set internally through a peak detector that automatically adjusts gain (200 Ohms to 7K Ohms) keeping the output signal linear over the dynamic range.
