[time-nuts] LTC6957 internal architecture

[Bruce Griffiths]

The following patent hints that the LTC6957 front end 
probably consists of several cascaded long tailed pair 
differential amplifier stages each with a selectable 
bandwidth set by capacitors shunting the collector load 
resistors. : US8319551
The input limiter is in effect a Collins style limiter with 
selectable bandwidth for each stage to reduce the noise 
with respect to a comparator which typically has several 
high gain wide bandwidth cascaded differential amplifier 
stages.
