Description
Technical field
The present invention relates to integrated circuit fields, are converted more particularly to a kind of radio frequency inductive of manufacture on the semiconductor device
Device.
Background technology
Inductance is that alternating flux, the magnetic of conducting wire are generated within and around conducting wire when passing through alternating current in conducting wire
Flux and the ratio between the electric current for generating this magnetic flux.
When passing through DC current in inductance, around the fixed magnetic line of force is only presented, not time to time change；But work as
When passing through alternating current in coil, around will show the magnetic line of force of time to time change.According to faraday electromagnetic induction
Law --- magnetic gives birth to electricity to analyze：The magnetic line of force of variation will produce induced potential at coil both ends, this induced potential is equivalent to
One " new power ".When forming closed circuit, this induced potential will generate induced current.Induced electricity is known by Lenz's law
Magnetic line of force total amount caused by stream will try hard to prevent the variation of the original magnetic line of force.Since the variation of the original magnetic line of force derives from additional friendship
The variation of variable power source, therefore in terms of objective effect, inductance coil has the characteristic for preventing curent change in alternating current circuit.Inductance coil has
The characteristic similar with the inertia phase in mechanics is electrically being named as " self-induction ", is usually pulling open knife switch or is connecting lock
The moment of knife-like switch, it may occur that spark is generated here it is self inductance caused by very high induced potential.
With the continuous renewal that inductance is applied in radio circuit, a kind of radio frequency inductive transformation that can change inductance is needed
Device.
Invention content
The technical problem to be solved in the present invention is to provide the radio frequency electricals that a kind of manufacture can change inductance on the semiconductor device
Feel converter.
In order to solve the above technical problems, a kind of radio frequency inductive converter provided by the invention, including：First inductance L1,
Two inductance L2 and switching device S；
First inductance L1 is set to semiconductor devices first layer B1, the second inductance L2 and is set to the semiconductor devices second layer
B2；The distance between two inductance are d；Switching device S is connected in parallel on the second both ends inductance L2；
It is further improved, the first inductance L1 and the second inductance L2 have overlapping region in vertical direction.
It is further improved, the first inductance L1 and the second inductance L2 are the identical structure of shape on coiling Butut.
It is further improved, the first inductance L1 and the second inductance L2 are the entirely different structure of shape on coiling Butut.
It is further improved, the first inductance L1 is in vertical direction completely obscured second inductance L2 or the second inductance L2 in vertical side
To completely obscured first inductance L1.
It is further improved, switching device S is diode, triode, HEMT pipes or metal-oxide-semiconductor.
The operation principle of the present invention：
Assuming that the mutual inductance between the first inductance L1 and the second inductance L2 is M, between the first inductance L1 and the second inductance L2
Mutual inductance is k, then the relationship between them is M=k (L1*L2) 1/2.
Remember that the first both ends inductance L1 alternating voltage is V1, the alternating current passed through on the first inductance L1 is I1, the second inductance
The both ends L2 alternating voltage is V2, and the alternating current passed through on the second inductance L2 is I2.
Due to the effect of mutual inductance,
V1=j ω * L1*I1+j ω * M*I2
V2=j ω * M*I1+j ω * L2*I2
When inductance converter is off state, switching device S is off state, at this time due to the second inductance L2
Interior that circuit is not present, the working condition of the first inductance L1 is not influenced by the second inductance L2.
When inductance converter is in running order, switching device S is conducting state, at this time the two of the second inductance L2
Terminal shortcircuit.At this point, due to V2=0, the first both ends inductance L1 equivalent inductance quantitative change is caused to be changed to (L1-M2/L2), i.e. the first inductance
The equivalent inductance amount of L1 becomes smaller.In extreme circumstances, if mutual inductance k=1, M2=L1*L2, the first inductance L1's is equivalent
Inductance value can become 0.
Inductance converter controls the inductance value of the first inductance L1 using the second inductance L2 and switching device S as a result, makes it
It can change between two kinds of inductance values, to adapt to the optimum condition of inductance value needed for the first inductance L1 operating circuits.The present invention
Radio frequency inductive converter can change inductance, have compared with prior art in radio circuit and more high practicability and more extensively answer
Use range.
