Abstract
  • Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart from being capable of handling a wide range of data rates, the transceivers should have low power consumption (mW/Gbps) and be fully integrated. This work discusses enabling techniques to implement such transceivers. Specifically, three designs: (1) a 0.5-4 Gbps serial link which uses current recycling to reduce power dissipation and (2) a 0.5-2.5 Gbps reference-less clock and data recovery circuit which uses a novel frequency detector to achieve unlimited acquisition range and (3) a 2-4 Gbps low power receiver architecture capable of resolving multiple signalling formats with a simplified XOR based phase rotating PLL will be presented. All the three circuit topologies are highly digital and aim to address the requirements of wide operating range, low power dissipation while being fully integrated. Measured results obtained from the prototypes illustrate the effectiveness of the proposed design techniques.
