ABSTRACT:
A bootstrap voltage generating circuit includes a bias circuit having a first end coupled to a first power source node having an operation voltage, and a second end coupled to a low voltage reference potential, wherein a voltage at the first end is related to the operation voltage in a non-linear way; a charging capacitor having a first end coupled to the load circuit; a charging path between a second end of the charging capacitor and the first end of the bias circuit, wherein the charging path is responsive to a clock signal; a discharging path between the second end of the charging capacitor and the low voltage reference potential, wherein the discharging path is responsive to the clock signal; and a switch circuit connected to the first end of the charging capacitor for setting a voltage thereon, wherein the switch circuit is responsive to the clock signal.
