Integrated circuit device implementing 90-degree phase shifter capable of generating output signals having phase difference therebetween at improved accuracy |
摘要 |
Disclosed is an integrated circuit device in which a 90-degree phase shifter is implemented. The 90-degree phase shifter includes four input capacitors all having equal capacitance and four output capacitors all having equal capacitance. The input capacitors and the output capacitors are alternately arranged in a loop-shape array in plan view. Eight resistors of the 90-degree phase shifter are arranged inside the annular shape in which the capacitors are arranged.
