8.3.2 Ultralow Charge Injection
The TMUX6104 is implemented with simple transmission gate topology, as shown in Figure 30. Any mismatch in the stray capacitance associated with the NMOS and PMOS causes an output level change whenever the switch is opened or closed.
Figure 30. Transmission Gate Topology The TMUX6119 utilizes special charge-injection cancellation circuitry that reduces the source (Sx) to drain (D) charge injection to as low as –0.35 pC at VS = 0 V, and –0.41 pC in the full signal range, as shown in Figure 31.
Figure 31. Source-to-Drain Charge Injection vs Source Voltage The drain (D)-to-source (Sx) charge injection becomes important when the device is used as a demultiplexer (demux), where the drain (D) becomes the input and the source (Sx) becomes the output. Figure 32 shows the drain-to-source charge injection across the full signal range.
