A transmitter and method is provided for digitally upconverting a baseband digital signal to a modulated intermediate frequency digital signal and sigma-delta modulating the IF digital signal. Various aspects of the present invention may comprise determining communication configuration information desired for the access point. Once inserted between interspinous processes, the implant acts to limit extension of the spine without inhibiting the flexion of the spinal column. In a particular embodiment, a super frame format is used where HIPERLAN transmissions are offered the highest level of protection possible within 802. The second Bluetooth device establishes a Bluetooth communication channel with the first Bluetooth device, using the extracted authentication information. The driver circuit includes a pull-up circuit and a pull-down circuit, each having two or more current paths that either source currents to or sink currents from the output node.
