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.

Using the unique "Smart Detector" function, the receiver provides fast scanning using only the peak detector.
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).

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.
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.
001 ps RMS on a 10 GHz clock buffer -- WIDE OFFSET: up to 500 MHz -- TRUE P-P JITTER: selectable mask filters and peak to peak detector -- EASE OF USE: "AUTO" functions -- PLUG-IN ARCHITECTURE: compact and always upgradeable
In addition to the electronic dispersion compensation engine for Chromatic and Polarization Mode Dispersion, the S3394 provides essential features and functions such as a programmable Bessel Filter, peak detector, linear gain control amplifier, a low-pass filter, and a high-performance CDR/DeMux with threshold and phase adjust capabilities running off a convenient positive 1.
A PLL synthesizer, a crystal oscillator, a limiter with RSSI generator, a data filter, a data comparator and a peak detector are also on the silicon.
The QP2111 promises to regenerate interest in using LM111-based dual comparators for numerous precision applications including zero crossing detectors, voltage-to-frequency converters, free-running mulitvibrators, voltage controlled oscillators (VCOs), crystal oscillator controllers, precision squarers, low voltage adjustable reference supplies, positive (or negative) peak detectors, and precision photodiode comparators, among others.
This PSoC netseminar will focus on the peripheral functions that are made possible by the switched-capacitor blocks, including peak detectors, rectifiers, RMS-to-DC converters, integrators, analog-to-analog converters (AACs), digital-to-analog converters (DACs), and analog-to-digital converters (ADCs).
