Abstract
An activation circuit which can realize both of area reduction and current consumption reduction by more preferred embodiments. The activation circuit has an N-type MOS transistor having a gate terminal connected to a ground and having a threshold voltage in a vicinity of 0 V and a resistor interposed between a source terminal of the MOS transistor and a ground, wherein an electric potential of a drain terminal of the MOS transistor is controlled depending on a first signal output from a device serving as a drive target, and transmission of a second signal for activating the device is controlled depending on the electric potential of the drain terminal.
