Abstract:
A method of calibrating a boost circuit includes: resetting a load to a reference voltage; supplying a charging voltage to the load through a boost circuit for a driving time such that charge sharing is performed in the load; comparing a voltage of the load after the charge sharing with a target voltage; and adjusting a duration of the driving time according to a result of the comparing.
