Title:
【発明の名称】固体撮像装置のパルス発生回路
Document Type and Number:
Japanese Patent JP2838878
Kind Code:
B2
Abstract:
PURPOSE:To prevent the shape of the leading edge of the frequency division output of a second frequency division circuit from being set differently at every cycle by offsetting the change of a current on an output buffer by the influence of the frequency division output of the second frequency division circuit different at every cycle in which the change of the current on the output buffer is affected on the frequency division output of the second frequency division circuit. CONSTITUTION:The influence different at every cycle of the pulse of 8/5fsc of the second frequency division circuit 6 in which the change of the current on the output buffer 3 by a pulse of 4fsc outputted from a first frequency division circuit 2 is affected on the pulse of 8/5fsc outputted from the second frequency division circuit 6 is offset by the influence different at every cycle of 8/5fsc of the second frequency division circuit 6 in which the change of the current on the output buffer 5 by the output of a phase inversion circuit 4 having a phase difference (pi) for the pulse of 4fsc of the first frequency division circuit 2.
