Abstract
This paper presents a 10-Gb/s clock and data re-
covery (CDR) and demultiplexer IC in a 0.13-
m CMOS process.
The CDR uses a new quarter-rate linear phase detector, a new
data recovery circuit, and a four-phase 2.5-GHz LC quadrature
voltage-controlled oscillator for both wide phase error pulses and
low power consumption. The chip consumes 100 mA from a 1.2-V
core supply and 205 mA from a 2.5-V I/O supply including 18
preamplifiers and low voltage differential signal (LVDS) drivers.
