Abstract
This paper describes a high data rate proximity transmitter design for high resolution smartphone-mirrored display applications. A 2 Gb/s transmitter is designed with a low transmission power of –70 ㏈m/㎒ and a wide bandwidth of nearly 3 ㎓. A digital pre-correction method is employed in the transmitter to mitigate the inter-symbol interference problem. A carrier-based digital pulse shaping and a reconfigurable digital envelope generation methods are employed for robust operation by utilizing 20 phases from a 2 ㎓ phase-locked loop. A 6.5-9.5 ㎓ transmitter implemented in 65 ㎚ CMOS achieves the maximum data rate of 2 Gb/s, consuming only 7.6 ㎽ from a 1 V supply.
