Abstract

The invention discloses a millimeter wave high-speed frequency divider, and relates to the field of millimeter wave integrated circuits. The millimeter wave high-speed frequency divider is a frequency divider module applied in a millimeter wave transceiver chip, and solves the technical problems that the existing high-speed frequency divider is too large in area and too narrow in frequency division range. The millimeter wave high-speed frequency divider comprises four simple D triggers connected in sequence into a ring. The millimeter wave high-speed frequency divider not provided with passive devices such as an inductor occupying large area has the technical advantages of small area and large frequency division range.

Description

technical field [0001] The invention relates to the field of millimeter-wave integrated circuits, in particular to a millimeter-wave high-speed frequency divider, which is a frequency divider module used in millimeter-wave transceiver chips. Background technique [0002] Because the millimeter-wave frequency band has a high available bandwidth and high detection accuracy, millimeter-wave chips are widely used in wireless communication, radar, guidance, remote sensing technology, radio astronomy, and electronic countermeasures. In recent years, with the successive opening up of millimeter wave frequency bands, millimeter wave chips have become a hot spot. How to design a high-speed frequency divider with low power consumption, small area and large frequency division range has always been a subject worth studying. [0003] At present, the more common millimeter-wave high-speed frequency divider is an injection-locked frequency divider. In the injection-locked frequency divid...
