WebJun 13, 2015 · A floating state is defined when the voltage at a gate is determined by the leakage current of the device. Unused CMOS inputs which are left floating will experience a gradual charging of the gate input capacitance. A floating input may see an increase in static current, or if the gate voltage reaches the threshold level start to oscillate.
