A wireless network device having active and inactive modes comprises a
clock generating module that generates a first clock signal having a
first clock rate. A voltage supply module generates a first voltage level
and a second voltage level that is less than the first voltage level. A
first digital module receives the first clock rate and the first voltage
level during the active mode, receives the second voltage level during
the inactive mode and does not receive the first clock signal during the
inactive mode. A first analog module communicates with the voltage supply
module and has reduced current consumption during the inactive mode.
