ABSTRACT:
A latchable comparator including a comparator and a circuit having a reset input. When the comparator produces a first state, it is latched when the reset input is in the non-reset state. In this state, the comparator receives a comparison signal having a high or low value and a latch signal being outside the range of voltages extending between the low and high values. A reset signal causes the latch signal to be replaced by a comparator reference signal. Further disclosed is a latchable comparator including a comparator and a flip-flop. The comparator has a ramp input, a control input, a first reference input and a second reference input. The flip-flop provides latch signals to each of the first and second reference inputs when its reset input is in the non-reset state and said comparator is generating a first state and maintains the latch signals until a reset signal is received.
