Abstract:
A drive circuit applying two or more drive voltages to a charge transfer unit includes at least one current mirror circuit that receives a reference current and outputs a predetermined current; at least one switch circuit that switches the current output from the at least one current mirror circuit to apply the multiple drive voltages to the charge transfer unit; and at least one time constant circuit that gives a predetermined time constant to the reference current in the switching by the switch circuit.
