Abstract

PURPOSE:To obtain a phase shifting circuit of 0 deg.-360 deg. consisting of a semiconductor device possible to be integrated by generating an output signal in which phase shift proportional to weight is added on an input signal by a weighting control signal. CONSTITUTION:A separation part 31 generates a 0-phase separation signal Sso and pi/2-phase separation signal Ss90 having a phase difference of 90 deg. with each other by receiving the input signal Sin, and a distribution part 32 generates a 0-phase distribution signal Sdo, a pi/2-phase distribution signal Sd90, and a pi-phase distribution signal Sd180 having the phase differences of 90 deg. and 180 deg. with each other. A weighting synthetic part 33 separates the signal to plural kinds of phase shift signals having respective phase range individually, and also, performs the synthesis of the signals after weighting an amplitude component, respectively, and the phase shift circuit 30 decides the weighting by receiving the weighting control signal Sw from the outside, and the quantity of phase shift of an Sout for the Sin by the weighting. In such a way, since the quantity of the phase shift can be controlled by an arithmetic operation, no variable L or no varable C is interposed, and it is possible to perform the phase shift extending over 0 deg.-360 deg. only by the semiconductor device.
