Abstract: A zero current detection device is proposed. The device may include a scaling circuit unit configured to generate a first voltage which is scaled from a target voltage. The device may also include a mirroring circuit unit configured to generate a mirroring current when the first voltage is higher than or equal to a reference voltage. The device may further include a comparator circuit unit configured to compare the target voltage and a ground voltage when the mirroring current is input.
