Abstract:
An integrated circuit, comprising:a voltage reference circuit operably coupled to an input signal, wherein the voltage reference circuit produces a reference voltage;a translator circuit operably coupled to the input signal, wherein the translator circuit produces a translated voltage;a comparator circuit operably coupled to the voltage reference circuit and the translator circuit, wherein the comparator circuit produces a comparator output based on the comparison of the reference voltage and the translated voltage, further wherein the comparator output circuit causes the comparator output to have an original state prior to comparison of the reference voltage and the translated voltage, the comparator circuit causes the comparator output to assume a second state while the magnitude of the reference voltage is larger than the magnitude of the translated voltage, and the comparator circuit causes the comparator output to return to the original state when the magnitude of the translated voltage reaches the same level as the magnitude of the reference voltage; anda pulse shaper circuit operably coupled to the comparator circuit, wherein the pulse shaper circuit produces a resetting pulse of the second state in response to the comparator output assuming the second state, further wherein the resetting pulse maintains the second state for a fixed duration beyond when the comparator output returns to the original state.
