Abstract

Method and apparatus for providing a data stream generator that generates a data stream associated with a monitored analyte level, and a radio frequency logic portion operatively coupled to the data stream generator, the radio frequency logic portion configured to generate a radio frequency data stream based on the data stream generated from the data stream generator, the radio frequency logic portion further including one or more finite state machines and a plurality of discrete digital logic circuits, the one or more finite state machines configured to control the plurality of digital logic circuits to generate the radio frequency data stream for wireless communication are provided. Systems and kits incorporating the same are also provided.

Claims

1. A glucose monitoring device, comprising:

an in vivo glucose sensor; and

sensor electronics coupleable to the in vivo glucose sensor to receive signals generated by the in vivo glucose sensor, the sensor electronics including;

a data communication unit;

a transmit state machine that issues a build packet command and a send packet command; and

a data stream generator that includes a finite state machine that builds a data packet based on the signals generated by the in vivo sensor and in response to the build packet command, wherein the finite state machine sends the built data packet to the data communication unit in response to the send packet command from the transmit state machine for communication to a remote location.
