Abstract: A current control circuit and a bias generator including the current control circuit are provided. The bias generator may include a current mirror circuit configured to generate one of a first current and a second current based on a reference current; a switch circuit configured to transfer one of the first current and the second current to a variable resistor; an operational amplifier including a first input node connected to the switch circuit, a second input node that receives a reference voltage, and an output node that outputs a bias voltage; and the variable resistor connected between the first input node and the output node of the operational amplifier. By switching operation of the switch circuit, a direction in which the first current flows in the variable resistor may be different from a direction in which the second current flows in the variable resistor.

Abstract: A method and an apparatus for controlling a threshold voltage are provided. The method includes receiving noise event signals from a sensing core, the sensing core sensing a portion of a moving object, and generating an event signal. The method further includes determining a type of the noise event signals, determining a number of the noise event signals based on the type of the noise event signals, determining whether the number of the noise event signals satisfies a condition, and controlling a threshold voltage value corresponding to the noise event signals in response to the determining that the number of the noise event signals does not satisfy the condition.
