Claim:
1. A voltage generator, comprising an oscillator comprising an output; a charge pump comprising an input and an output, the input of the charge pump being coupled to the output of the oscillator; a smoothing capacitor; a resistor having an input end and an output end, wherein the input end is coupled to the charge pump and the output end is coupled to the smoothing capacitor; a shorting element connected in parallel with the resistor and which, when turned on, causes the resistor to be at least partially bypassed; and an additional resistor coupled between a node, defined by a connection between the resistor and the charge pump, and the shorting element, wherein the voltage generator is configured to supply voltage to a radio frequency (RF) switch via the smoothing capacitor, and a frequency of the oscillator is controlled to be faster during a switching period of the RF switch.
