摘要
This invention makes the change in current drawn from the power grid in an integrated circuit gradual by sequencing the power switch chains differently for both power up and power down. During power up, this invention establishes a reasonable connection with the power grid through a series of weak power switches and then starts turning on the strong power switches. During power down, this invention reverses the process. Strong switches are all turned off before turning off the weak switches.
