Abstract: In one embodiment, a radio receiver includes: a programmable frequency synthesizer to generate a first clock signal; a first frequency divider to divide the first clock signal to generate a master clock signal; a second frequency divider to divide the master clock signal to generate a mixing signal; and a mixer to downconvert a radio frequency (RF) signal to a second frequency signal using the mixing signal. A voltage converter to couple to the radio receiver includes a switch controllable to switchably couple a first voltage to a storage device and a pulse generator to generate at least one pulse pair formed of a first pulse and a second pulse substantially identical to the first pulse, when a second voltage is less than a first threshold voltage, the second pulse separated from the first pulse by a pulse separation interval.
