Embodiment Construction

[0016] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention. The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0017] figure 1 It is a structural schematic diagram of the low-power on-chip vector modulation phase shifter described in the present invention. The vector modulation phase shifter proposed by the invention is formed by cascading a lumped Lange coupler and a vector modulator. Among them, the lumped Lange coupler decomposes the input RF signal IN into two orthogonal channels VINI and VINQ, and the vector modulator adjusts the polarity and gain of the I channel and the Q channel accord...

Abstract

The invention relates to the technical field of integrated circuits, in particular to an on-chip vector modulation phase shifter, which generates a phase shift in the range of 0-360° through phase interpolation, and has high phase shift accuracy and low phase shift error . Compared with the traditional vector modulation phase shifter, the vector modulation phase shifter of the present invention can reduce power consumption by 50%, and has the advantages of small area, low cost, simple design, broadband input impedance matching and the like.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an on-chip vector modulation phase shifter. Background technique [0002] With the continuous development of integrated circuit production technology, the phased array system using complementary metal oxide semiconductor technology has achieved high integration and low cost. widely used. The phase shifter is a key component of phased array radar. There are mainly two implementation methods: passive structure and active structure. The key technical indicators include phase shift range, phase shift accuracy, phase error, insertion loss, gain error, and input matching. , area and power consumption etc. Active phase shifters generally use the quadrature vector synthesis method. This method first decomposes the input RF signal into quadrature signals, then adjusts the amplitudes of the quadrature signals respectively, and finally synthesizes the two quadrature signals to...
