Abstract:
Traditionally, latched comparators have suffered from performance problems related to exposure of the latch to load capacitances. Even attempts to isolate the latch from the load capacitances by way of resistors has resulted in performance problems (namely, voltage swing degradation). Here, however, a latched comparator is provided that employs inductors to generally provide isolation from load capacitances, which generally improves performance. Moreover, the latch has been modified to accommodate the inductors during a track period (namely, provision of grounding paths).
