Abstract
Disclosed is a phase shift circuit including an input circuit for generating first to fourth internal signals based on an in-phase signal, a complementary in-phase signal, a quadrature phase signal, and a complementary quadrature phase signal and a switching circuit for outputting first to fourth shift signals based on the first to fourth internal signals. The input circuit includes a first transistor connected between a ground node and a first node to operate based on the in-phase signal and the first bias signal, a second transistor connected between the ground node and a second node to operate based on the complementary in-phase signal and the first bias signal, a third transistor connected between the ground node and the first node to operate based on the second bias signal, and a fourth transistor connected between the ground node and the second node to operate based on the second bias signal.
