Abstract
A custom IC has been developed for the acquisition, digitization and telemetry of biological signals in the laboratory. This single chip system consists of a preamplifier, analog to digital converter and frequency shift keyed telemetry. The IC is 2.25 mm×2.25 mm and consumes 10 mW of power at a power supply voltage of 2.5 V. Data can be transmitted several meters. No off chip components are required except a miniature battery and a straight wire antenna as short as 2 cm. The IC is fabricated in a standard digital CMOS process without a second level of poly-silicon; current mode techniques are used to overcome the lack of linear capacitors.
