Robust high-accuracy high-speed continuous-time CMOS current comparator
(Institution of Engineering and Technology, 1997)
The authors present a CMOS current comparator which employs nonlinear negative feedback to obtain high-accuracy (down to 1.5pA) and high-speed for low input currents (8ns at 50nA). The new structure features a speed ...

Mismatch distance term compensation in centroid configurations with nonzero-area devices
(Institute of Electrical and Electronics Engineers, 1997)
This paper presents an analytical approach to distance term compensation in mismatch models of integrated devices. Firstly, the conditions that minimize parameter mismatch are examined under the assumption of zero-area ...
