摘要
This paper presents an inductive telemetry system useful for isolated applications that have to be powered and/or controlled from outside. The transmitter is based on a Class-E amplifier with ASK modulation generated with a resonant modulation to obtain the different levels to transmit. In the receiver two possible configurations, parallel and serial, are studied and the serial configuration is proposed to reduce the effect of the rectifier and the filter over the received signal. Also an ASK demodulator is fabricated in an ASIC. All the system (transmitter-receiver) has been tested and a 60% of efficiency in power transmission is obtained at a distance of 10 mm. For the data link a bit rate 1 Mbps with a carrier of 8 MHz at a distance of 20 mm has been obtained. (c) 2007 Elsevier Ltd. All rights reserved.
