Abstract
A peak/bottom detection circuit is disclosed. A comparator compares a voltage of one of three or more capacitors with an input voltage. A calculation amplifier amplifies the voltage of one of the three or more capacitors. Each of three or more switches respectively corresponding to the three or more capacitors connects a corresponding capacitor among the three or more capacitors to one of the comparator, the calculation amplifier, and a source of the input voltage. A controller generates control signals for sequentially switching connection destinations of the three or more capacitors and to supply the control signals to the three or more switches, respectively, in which the connection destinations of three capacitors among the three or more capacitors are different from each other.
