Parameters that Affect Comparator Propagation Delay Measurements

Kevin B. Scott - Senior Strategic Marketing Engineer Nov 4th 2015
One of the key specifications for a comparator is propagation delay - the amount of time it takes for a signal propagate from the comparator input to the output. Whether as a threshold detector in a battery powered application, or on a high speed signal processing board, the comparator's propagation delay is often the first ...

Industry's Fastest Comparators Drive 1.8V Logic Beyond 280MHz

Mar 11th 2015
MILPITAS, CA - March 11, 2015 - Linear Technology Corporation announces the LTC6752 family of comparators with fast rise and fall times of 1.2ns and a toggle frequency of 280MHz, making them the fastest CMOS output comparators available today. Designed for driving logic levels from 3.3V down to 1.8V, the LTC6752 exhibits only ...

Versatile Comparators Enable Fast Signal Detection, Level Translation and Clock Recovery

Asit Shankar - Senior Design Engineer Jan 27th 2015
In this video, a new high speed CMOS output comparator family, the LTC6752, is introduced. The comparators exhibit extremely high toggle rates of 280 MHz and very low propagation delays of only 2.9ns. An overview of important features and specifications is presented. A brief description of each of the five members of the family ...

LTC6752 Pulse Stretcher Circuit/Monostable Multivibrator

Dec 16th 2014
For detecting short pulses from a single sensor, a pulse stretcher is often required. The circuit of the figure above acts as a one-shot, stretching the width of an incoming pulse to a consistent ~100ns. The circuit works as follows: Comparator U1 functions as a threshold detector, and Comparator U2 functions as a one-shot. ...

LTC6752 Optical Receiver Circuit

Dec 16th 2014
The LTC6752, along with a high speed high performance FET input operational amplifier like the LTC6268, can be used to implement an optical receiver as shown above. The figure shows the output of the LTC6268 driving the –IN pin of the LTC6752-2, the +IN pin of the LTC6752-2, and the LTC6752 output. The photodiode is ...

LTC6752 200MHz Clock Restoration/Level Shifting

Dec 16th 2014
High speed comparators are often used in digital systems to recover distorted clock waveforms. The separate input/ output supplies feature of the LTC6752-2 allows it to be used in applications where signals need to be shifted from one voltage domain to another. The circuit above can perform both recovery and level translation ...
