Abstract: An improved contact image sensor (CIS) which uses a two-phase shift register is disclosed. The shift register is clocked by both phases of the clock signal, thereby doubling its speed. A transmission gate in the shift register is eliminated and combined with one of the inverters to allow two-phase operation and reduce the number of transistors required to implement the shift register.
