ABSTRACT:
An analog comparator comprising a generator circuit which generates an input signal voltage having a certain slew rate, a setting circuit which sets a target or desired voltage, another setting circuit which sets a threshold voltage corresponding to the slew rate of the input signal voltage and an ambient temperature, and a comparison circuit which receives the input signal voltage, the target voltage and the threshold voltage and which delivers a coincidence timing signal upon detecting that the input signal voltage has reached a voltage shifting by the threshold voltage from the target voltage.
