Abstract
An active current source load of a fully differential amplifier which is converted into a transconductance (g) 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 gat dc and becomes g+(g+g) at high frequency which triples the UGB when g=g.
