Abstract: In one embodiment, an electrical circuit module may include a bootstrap capacitor connected to a bootstrap-capacitor charging switch. A first signal channel may include a first sampling switch and a first control switch that controls a first connection between the bootstrap capacitor and a first control input of the first sampling switch. A second signal channel may include a second sampling switch and a second control switch that controls a second connection between the bootstrap capacitor and a second control input of the second sampling switch. The bootstrap capacitor may be charged during a first operation phase during which the bootstrap-capacitor charging switch is turned on. The first control switch of the first signal channel may be turned on during a first sub-phase of a second operation phase, and the second control switch of the second signal channel is turned on during a second sub-phase of the second operation phase.
