Abstract: A band-switching network includes a dual-band balun and a switch network. The dual-band balun includes a first output and a second output. The switch network includes a first switch and a second switch in which an input to the first switch is coupled to the first output and an input to the second switch is coupled to the second balanced output. The dual-band balun further includes a primary coil, a first secondary coil and a second secondary coil in which the first secondary coil is coupled to the first balanced output and the second secondary coil is coupled to the second balanced output. In one embodiment, the primary coil and the first secondary coil are coupled by a first coupling factor k1, and the primary coil and the second secondary coil are coupled by a second coupling factor k2 that is different from the first coupling factor k1.

Abstract: Methods and apparatuses are provided in which a level shifter of a digital control circuit for a switchable voltage supply circuit shifts a domain level of a first input. A first inverter of the digital control circuit inverts output of the first level shifter to output a first gain voltage to turn on a first switch of the switchable voltage supply circuit or output a second gain voltage to turn off the first switch. A second inverter of the digital control circuit inverts a second input to output a third gain voltage to turn on a second switch of the switchable voltage supply circuit or output a fourth gain voltage to turn off the second switch. The first gain voltage is greater than the third gain voltage.
