Abstract
A sensing circuit includes initialization switches, shield switches, signal selection switches and a signal current integrator. The initialization switches apply an initialization voltage to sensing channels based on an initialization control signal. The shield switches apply a shield voltage different from the initialization voltage to the sensing channels based on shield control signals. The signal selection switches sequentially output sensing currents received from the sensing channels based on sensing control signals. The signal current integrator sequentially converts the sensing currents into sensing voltages. When a target sensing current is to be detected from a target sensing channel from the sensing channels, the shield voltage is applied to at least one shield sensing channel adjacent to the target sensing channel from the sensing channels.
