Digital transmitter, digital transceiver and control method thereof

Abstract

A digital transmitter, a digital receiver and a control method therefor. The control method comprises: replenishing energy to an inductor (L) and a load capacitor (CL) by means of an electric energy replenishment circuit, completely transferring, by an electric energy transfer circuit, the electric energy of the inductor to the load capacitor, so as to non-destructively drive the load capacitor to a high level, then connecting the load capacitor to a first accentuator circuit, keeping a signal output at a high level of a low resistance, then transferring all electric energy on the load capacitor to the inductor by means of the electric energy transfer circuit, recovering the electric energy of the inductor onto a power source by means of an electric energy recovery circuit, so as to perform electric energy recovery while the load capacitor is driven, connecting the load capacitor to a second accentuator circuit, and keeping a signal output at a low level of a low resistance. By means of the method, non-destructive transmission of data 1 and data 0, reduction of working energy consumption of the power source and prolonging of the service life of the digital transmitter can be realized by non-destructively driving the load capacitor.

Description

technical field [0001] The present invention relates to the field of digital signals, in particular to a digital transmitter, a digital transceiver and a control method for a digital transmitter Background technique [0002] In the transmission of digital signals, digital signals are usually processed by a digital transmitter and sent, and then received by a data receiver. Digital transmitters are usually paired with digital receivers. [0003] As the frequency of the digital signal increases, the digital output driving the load capacitor needs to perform non-stop charging and discharging actions, which will consume a lot of power. In the prior art, the digital transmitter uses the power supply voltage to directly charge the load capacitor. This method consumes a lot of power and consumes a lot of power energy, which is not conducive to reducing costs and improving the utilization rate of the power supply. [0004] Therefore, it is necessary to propose a method for driving...
