| 摘要 |
A phase shift circuit includes a first phase shifter, second phase shifter, and adder. The first phase shifter receives an input signal and obtains first and second intermediate phase shift signals having different phases. The second phase shifter obtains first and second outputs by shifting phases of the first and second intermediate phase shift signals. The adder generates a phase shift output signal by adding the first and second outputs from the second phase shifter. A phase shifting device, oscillation circuit, and image rejection mixer are also disclosed. <IMAGE> |
