Abstract :
Charge injection in MOS switches has been analyzed. The analysis has been extended to the general case of including source resistance and source capacitance. Universal plots of percentage channel charge injected are presented. Normalized variables are used to facilitate usage of the plots. A small-geometry switch, slow switching rate, and small source resistance can help reduce the charge injection effect.
