A new passive CMOS telemetry chip to receive power and transmit data for a wide range of sensor applications

A new full integrated telemetry chip with the possibility of integrated micro coils on the chip is presented. The telemetry chip receives the power for the sensor microsystem. Using a passive modulation technique the telemetry chip transmits measured data to the external power transmitter. In order to verify the performance of the telemetry chip, the transfer channel between the external transmitter and the receiver with the circuits of the telemetry chip have been simulated with SPICE. Measurements of a produced telemetry chip were made to confirm our technical concept and they verify the full operation of our telemetry chip.
