Abstract :
The authors present a CMOS current comparator which employs nonlinear negative feedback to obtain high-accuracy (down to 1.5 pA) and high-speed for low input currents (8 ns at 50 nA). The new structure features a speed improvement of more than two orders of magnitude for a 1 nA input current, when compared to the fastest reported to date
