Abstract

This paper describes the circuit and the layout of the shift register which can be used for a scanner of image sensor. P-well concentration and threshold voltage for proper iperation are calculated on the basso of the fixed process and the layout design. The calculation procedure of maximum operation frequency is also carried out. It is ascertained by SPICE simulation that the shift register produces the outputn pulse without threshold voltage loss up to 13MHz.
