Problems solved by technology

[0003] While existing transformers such as figure 1 As shown, the way the inductance is wound leads to inductance asymmetry, which makes it difficult to apply to differential circuits
Furthermore, if it is applied to an oscillating circuit, the configuration of the capacitor needs to be set separately, which will increase a lot of area and increase the production cost

Abstract

The invention provides a transformer applicable to an oscillator and a winding method of the transformer. The transformer comprises a first coil and a second coil. The first coil is a first metal plane coil and is arranged in a winding mode along a preset three-dimensional area which comprises a first layer and a second layer, and the first layer and the second layer each comprises a left side area and a right side area; the first coil is arranged in a winding mode along the first end of the left side area of the first layer, passes through a first center line and then is arranged in a winding mode along the right side area of the second layer till reaching the second end of the left side area of the second layer. The second coil is a second metal plane coil and is arranged in a winding mode along the preset three-dimensional area, the second coil is arranged in a winding mode along the first end of the right side area of the second layer, passes through a first center line and is arranged in a winding mode along the left side area of the second layer till reaching the second end of the right area of the first layer. A first center tap is arranged on the position, on a second center line of the right side area of the second layer, of the first coil, and a second center tap is arranged on the portion, on a second center line of the left side area of the second layer, of the second coil.

Description

technical field [0001] The invention relates to an electronic device; in particular, it relates to a transformer and a winding method suitable for an oscillator. Background technique [0002] figure 1 A schematic diagram of an existing transformer 100 is shown. A transformer is a four-terminal component that includes two inductors. And the transformer does not need a DC block because the primary coil and the secondary coil do not directly intersect. [0003] While existing transformers such as figure 1 As shown, the way the inductance is wound leads to inductance asymmetry, which makes it difficult to apply to differential circuits. Furthermore, if it is applied to an oscillating circuit, the configuration of the capacitor needs to be arranged separately, which will increase a lot of area and increase the production cost. [0004] Therefore, how to provide a transformer to make the inductance of the primary coil and the secondary coil symmetrical, and to save the area o...
