Patent ID: 8476935

Claim:
A comparator circuit comprising: an amplifier configured to compare a first input signal with a second input signal and to generate an output signal with reference to the comparison; a non-linear function having a single output only, the non-linear function being configured to receive each output signal generated by the amplifier and generate only a single output signal for the comparator circuit at the single output of the non-linear function; and a feedback loop having a MOSFET transistor with a gate, a source, and a drain, the gate being operably connected to the single output of the non-linear function and to a second input of the non-linear function, the feedback loop including a feedback limiting circuit having a capacitor connected in series between electrical ground and the drain of the MOSFET transistor, but not connected to the single output of the non-linear function, the capacitor of the feedback limiting circuit being configured to attenuate a feedback signal generated by the MOSFET transistor that is operably connected to the second input of the non-linear function during a transition of the output of the amplifier.
