A low-power transmitter design for inductive data link with class-F switching operation
نویسندگان
چکیده
This letter presents a new design method of a low-power transmitter for inductive link. The proposed method introduces the concept of class-F RF amplifiers into an inductive data link. The power dissipation of the class-F transmitter is analyzed for carrier and symbol transition. It is revealed that the proposed transmitter consumes extremely low power of less than 0.2 nJ/bit with BPSK modulation at 2.5M Sample/s and the communication distance of about 50 cm.

متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
