Abstract
The voltage comparator of the present invention comprises a sense amplifier connected to a latch. The sense amplifier has a first input terminal for connecting to the input voltage under consideration and a second input terminal for connecting to the reference voltage. The sense amplifier generates two voltages of opposite logic values (i.e., high or low). A latch accepts these two voltages and generates an output voltage that is indicative of whether the voltage under consideration is higher or lower than the reference voltage. In another embodiment, a signal conditioning circuit is used to reduce the transients in the input voltage under consideration and perform level shifting function.
