Abstract:
A circuit is disclosed. The circuit includes a current detecting FET, configured to generate a current signal indicative of the value of the current flowing therethrough, an operational transconductance amplifier (OTA) configured to output a current in response to the voltage of the current signal, and a resistor configured to receive the current and to generate a voltage in response to the received current, where the generated voltage is indicative of the value of the current flowing through the current detecting FET. The current detecting FET is configured to become nonconductive in response to the generated voltage indicating that the current flowing through the current detecting FET is greater than a threshold.
