Power gate circuit, solid-state imaging device, and camera system |
摘要 |
A power gate circuit includes: a power gate switch connected at least between a reference potential terminal of a circuit to be power-gated and a reference potential or between a power supply terminal of the circuit to be power-gated and a power supply; a capacity connected to a gate of the power gate switch; a pulse generating section supplying a pulse signal to the gate of the power gate switch according to a control signal; and a power gate control section outputting the control signal to the pulse generating section to supply the pulse signal to the gate of the power gate switch when the power gate switch is turned on and accumulating electrical charges in the capacity to control a gate potential of the power gate switch such that the potential gradually approaches a potential at which the power gate switch is turned on. |
