"Receiver-end hardware
is complicated. Every
improvement on this
hardware will not only
improve accuracy and
precision but also make
it easier to manufacture,
which will cut the cost ."

High-Speed, Low-Power Comparators with
Built-In Analog-to-Digital Converter
Maxim's comparators deliver high speed and low propagation delay and dispersion, which
are essential for precise measurement:
• Maxim's high-speed comparators have a propagation delay of only 280 ps. A low
overdrive dispersion of 25 ps is typical, with a delay dispersion of less than 10 ps. This
design helps achieve system resolution of less than 1 mm, a significant improvement
over the industry average of 2 to 3 mm.
• The input common-mode range of 1.5 V to V
DD
+ 0.1 V is compatible with popular
TIAs available on the market. The output stage is low-voltage differential signaling,
minimizing power dissipation that can interface directly with many field-programmable
gate arrays and central processing units.
• Comparator units are available in space-saving packaging as small as 1.2 mm × 0.8 mm
(WLP) and operate at −40°C to +125°C. These units run on a single supply of 2.7 V to 3.6
V. Their overall power consumption is less than 40 mW at 2.7 V supply.
