Assignee: SILERGY SEMICONDUCTOR TECHNOLOGY (HANGZHOU) LTD
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A digital isolator, comprising:
a) an encoding circuit configured to receive an input digital signal, and to generate an encoded signal according to the input digital signal;
b) an isolation element having a primary winding, a first secondary winding, and a second secondary winding, wherein the primary winding is connected with the encoding circuit and used for receiving the encoded signal, the first secondary winding and the second secondary winding are coupled with the primary winding in an electrically isolated manner, the first secondary winding is used for generating a first differential signal in phase with the encoded signal through electromagnetic induction, and the second secondary winding is used for generating a second differential signal in an opposite phase with the encoded signal through electromagnetic induction;
c) a differential circuit configured to receive the first differential signal and the second differential signal, and to generate a difference signal according to the first differential signal and the second differential signal; and
d) a decoding circuit coupled with the differential circuit, and being configured to receive the difference signal, and to generate a target digital signal after decoding.
