Abstract :
A complementary injection technique is proposed to enhance the overall performance of current mode logic (CML) dividers in this paper. With injection currents introduced by pMOSFETs, the equivalent injection efficiency of CML dividers are improved and thus CML dividers achieve a better performance. Extensive simulation results show that the proposed technique improves the division bandwidth of 24-GHz divide-by-2 CML divider by 5GHz, which is from 12GHz to 30GHz. The designed divide-by-2 CML frequency divider draws only 2-mA current from 1.2-V supply.
