This chapter will provide an overview of radio frequency (RF) telemetry systems by examining the
design requirements of two contrasting systems: a wireless system designed to support Fast Scan
Cyclic Voltammetry (FSCV) and a wireless system designed to support selective biosensors.
Traditionally, RF design and analog circuit design were very complicated endeavors. Component
interactions and non-ideal behaviors made such designs as much art as science. Today however,
there are a wide variety of analog integrated circuits with near ideal behavior, and self-contained RF
modules with built-in standardized protocols are available. In short, it is now very possible for a
neuroscientist, with little or no knowledge of telemetry, to design and construct robust wireless
acquisition systems.
