Abstract :
A silicon bipolar IC for data regeneration and clock recovery which includes a phase/frequency detector (PFD), a quadrature voltage controlled oscillator (VCO), and an MS D-flipflop (DFF) is presented. The VCO is based on a modified two stage ring oscillator approach and presents a wide tuning range of 2-to-9 GHz. Data regeneration at 8 Gb/s (with the onchip VCO) and PFD operation up to 15 Gb/s (with an external VCO) are demonstrated. The IC for clock and data regeneration was fabricated with a 25 GHz fT 0.4 μm emitter width bipolar process. The power dissipation is 2.25 W
