Recently, I study about current mode logic(CML) v.s charge steering logic(CSL).
So, I found paper "Charge Steering: A Low-Power Design Paradigm"[1],
and the paper is compare CML to CSL power,
there is thing so confuse me,
why CML circuit must provide a bandwidth of about 0.7rb, where rb is operation rate.
