  • Floating input detection
    Patent number: 10725118
    Abstract: A floating input detection method and circuits. A method for detecting a floating signal input terminal includes providing a common-mode input voltage to a first amplifier coupled to the signal input terminal, and providing an output signal generated by the first amplifier to: a non-inverting input of a second amplifier coupled to the signal input terminal, an inverting input of the second amplifier, coarse detection circuitry, and fine float detection circuitry. The method also includes comparing, by the coarse detection circuitry, the output signal to a first threshold voltage, and determining the signal input terminal to be not floating responsive to the comparing indicating that the output signal is greater than the first threshold voltage.
