An active current source load of a fully differential amplifier which is converted into a transconductance (gm) component also at higher frequency by feed-forwarding input signals to their gates. With signal coupling to gate, unity gain bandwidth (UGB) of the amplifier increases by a factor of two. In addition to this, the signal is coupled to source as well to achieve three-fold UGB enhancement. Thus, the effective trans-conductance is gmp at dc and becomes gmp+(gmngate+gmnsrc) at high frequency which triples the UGB when gmp=gmngate/src.
