Abstract :
This paper presents a 65nm mm-wave transmitter efficiently supporting QPSK modulation and phased array functionality with a proposed oscillator modulation technique. The design delivers an average output power of 1mW at 10Gb/s and 0.8mW at 14Gb/s while consuming 21.5mA DC current from a 1V supply. At 10Gb/s, an overall transmitter efficiency of 4.65% is achieved, representing ~1.8X improvement over prior art [1].
