Abstract:
Methods and systems for reliable bootstrapping switches may comprise sampling a received signal with a bootstrapping switch, where the bootstrapping switch comprises a switching metal-oxide semiconductor (MOS) transistor having a pull-down path coupled to a gate terminal of the switching MOS transistor. The pull-down path includes a diode-connected MOS transistor coupled in parallel with a second MOS transistor that couples the gate terminal of the switching MOS transistor to ground via third and fourth MOS transistors when the switching MOS transistor is in an OFF state. The third and fourth MOS transistors may be in series with the second MOS transistor. A gate terminal of the fourth transistor may be switched from ground to a supply voltage, VDD, to activate the pull-down path. A capacitor may be coupled between gate and source terminals of the switching MOS transistor to switch the switching MOS transistor to an ON state.
