Abstract:
A circuit includes an input stage that includes a first transistor device configured to generate a first output signal in response to a first bias current activating the first transistor device by exceeding a first threshold voltage of the first transistor device. A compensation stage includes a second transistor device coupled with a third transistor device. The second transistor device is activated in response to the first output signal exceeding a second threshold voltage of the second transistor device. The third transistor device is activated in response to activation of the second transistor device and a second bias current. The compensation stage is configured to generate a second output signal in response to the activation of the third transistor device. An output stage is configured to generate a reset signal in response to the second output signal exceeding a third threshold voltage.
