Title:
INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/147054
Kind Code:
A1
Abstract:
Provided is an integrated circuit, relating to the field of electronic technology, and being used to reduce the area occupied in an integrated circuit by a quadrature coupler. The quadrature coupler in the integrated circuit is provided with a positive-phase differential input port (INP), a negative-phase differential input port (INN), a positive-phase differential through port (TP), a negative-phase differential through port (TN), a positive-phase differential coupling port (CP), a negative-phase differential coupling port (CN), a positive-phase differential isolation port (ISOP) and a negative-phase differential isolation port (ISON). The quadrature coupler is provided with a first coil (L1), a second coil (L2), a third coil (L3) and a fourth coil (L4) which are coupled to each other. The positive-phase differential input port (INP) and the positive-phase differential through port (TP) are provided at both ends of the first coil (L1). The negative-phase differential input port (INN) and the negative-phase differential through port (TN) are provided at both ends of the second coil (L2). The positive-phase differential coupling port (CP) and the positive-phase differential isolation port (ISOP) are provided at both ends of the third coil (L3). The negative-phase differential coupling port (CN) and the negative-phase differential isolation port (ISON) are provided at both ends of the fourth coil (L4).
