SCDS424A December 2019 – March 2020 TMUX1237
PRODUCTION DATA.
The TMUX1237 has a transmission-gate topology. Any mismatch in capacitance between the NMOS and PMOS transistors results in a charge injected into the drain or source during the falling or rising edge of the gate signal. The amount of charge injected into the source or drain of the device is known as charge injection, and is denoted by the symbol QC. Figure 12 shows the setup used to measure charge injection from Drain (D) to Source (Sx).
