A LOW-POWER SYSTEM, TRANSMITTER, RECEIVER FOR SIGNAL ACQUISITION AND TRANSMISSION

摘要

The present invention relates to a low-power signal acquisition system for remote biosensing comprising: a converter unit, comprising ATCs connected in cascade as a chain for sampling and converting an input signal into an output signal of pulses with varying pulse-widths; a communication unit; and a control unit, arranged for receiving said output signal and control of said communication unit to transmit said output signal; wherein said communication module comprises a pulse harmonic modulation unit for driving said coupling link with a sharp impulse generating an oscillation pulse with rapid rise and slow decay, and generate a further oscillation pulse with predetermined delay for suppression of said oscillation pulse for forming a bitstream between said oscillation pulse and said further oscillation pulse to transmit said digital signal to said remote receiver; wherein said pulse harmonic modulation unit further comprises a damping switch a drive switch and an impulse generator.
