Abstract:
A boost circuit, comprising:an output; a precharge circuit connected to the output; a first capacitor having a first terminal and a second terminal, and the first terminal connected to the output; a first circuit connected to the second terminal of the first capacitor, and the first circuit defines one of a first state, a second state, and a third state, wherein in the first state the second terminal of the first capacitor is coupled to a first voltage supply, and in the second state the second terminal of the first capacitor is coupled to a second voltage supply, and in the third state the second terminal of the first capacitor is floating; a diode having a first terminal coupled to the output, and a second terminal; a second capacitor, having a first terminal coupled to the second terminal of the diode and having a second terminal; a second circuit connected to said second terminal of the second capacitor, wherein a tie delay separates a first onset of a first boosting operation of the first circuit and a second onset of a second boosting operation of the second circuit.
