Ultra-Low Charge Injection

Figure 8-1 shows how the TMUX620x devices have a transmission gate topology. Any mismatch in the stray capacitance associated with the NMOS and PMOS causes an output level change whenever the switch is opened or closed.

The TMUX620x contains specialized architecture to reduce charge injection on the Drain (Dx). To further reduce charge injection in a sensitive application, a compensation capacitor (Cp) can be added on the Source (S). This will push excess charge from the switch transition into the compensation capacitor on the Source (S) instead of the Drain (D). As a general rule, Cp should be 20x larger than the equivalent load capacitance on the Drain (D). Figure 8-2 shows charge injection variation with different compensation capacitors on the Source side. This plot was captured on the TMUX6219 as part of the TMUX62xx family with a 100pF load capacitance.
