Abstract :
A 1-16-Gb/s wide-range clock and data recovery (CDR) circuit is presented by using the proposed bidirectional frequency detector. This CDR circuit is fabricated in 0.13-μm CMOS technology, and its active area is 0.134 mm2 without a loop filter. The power consumption of this CDR circuit is 160 mW for a supply of 1.5 V. A modified interpolation voltage-controlled oscillator is presented, which covers from 4.9 to 10.2 GHz. A quadrature divider is used to generate accurate quadrature clocks.
