Definitions
- FIG. 3 is a block diagram of an exemplary base unit in accordance with an embodiment of the invention.
- FIG. 6 illustrates phase dithering in accordance with an embodiment of the invention.
- Exemplary System Figure 1 illustrates an exemplary system for communicating with a wireless sensor implanted within a body.
- the system includes a coupling loop 100, a base unit 102, a display device 104 and an input device 106, such as a keyboard.
- the coupling loop is formed from a band of copper. In one embodiment, the loop is eight inches in diameter.
- the coupling loop includes switching and filtering circuitry that is enclosed within a shielded box 101. The loop charges the sensor and then couples signals from the sensor into the receiver.
- the antenna can be shielded to attenuate in-band noise and electromagnetic emissions.
