Description
Technical field
The invention belongs to electronic circuit technology field, relate to a kind of level signal being converted to pulsed magnetic field
Circuit.
Background technology
For utilizing magnetic field to carry out the equipment of data communication, such as magnetoelectricity signal isolation coupling device, implanted
Cardiac pacemaker communication systems etc., need to convert electrical signals to magnetic signal in its work process, then by magnetic
Quick element detects and is read circuit collection, thus realizes signal transmission.Among these, " level-magnetic field " turns
Changing circuit is an indispensable component units.Existing scheme is by direct for field signal and level signal
Correspondence, such as: export field signal during high level, without field signal during low level；Or during high level
Output forward field signal, exports opposing magnetic field signal during low level.All there is the persistent period in above scheme
Longer electric current passes through magnet exciting coil, thus there is higher quiescent dissipation, it is difficult to be applied to low-power consumption just
Take equipment.
Summary of the invention
The present invention is directed to the deficiency that existing " level-magnetic field " change-over circuit exists, it is provided that a kind of by level letter
Number being converted to the circuit arrangement of pulsed magnetic field, the program can significantly reduce the quiescent dissipation of circuit.
The present invention solves the technical scheme that technical problem taked:
A kind of circuit that level signal is converted to pulsed magnetic field signal, comprises Anti-shaking circuit, delay circuit,
Coil driver A, coil driver B and magnet exciting coil.
Described Anti-shaking circuit is in signal input part, is used for suppressing input signal to shake.
Described delay circuit is connected between Anti-shaking circuit and coil driver B, makes input coil drive

Consumption, compared to other similar schemes, power consumption significantly reduces.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Of the present invention level signal is converted to the device of pulsed magnetic field as shown in Figure 1.This circuit by
Anti-shaking circuit 101, delay circuit 102, coil driver A103, coil driver B104 tetra-
Electronic circuit and magnet exciting coil 105 5 part composition.
Anti-shaking circuit 101 receives input signal 106, the suppression function to signal jitter possessed by it,
Eliminate the adverse effect that subsequent conditioning circuit is produced by the burr caused by signal self or external disturbance.
Anti-shaking circuit 101 exports two identical signals, and one of them signal directly inputs coil and drives
Galvanic electricity road A103, another signal first passes through delay circuit 102, then input coil drive circuit B104.
Therefore, the signal edge of input coil drive circuit B104 is relative to input coil drive circuit A103's
There is a specific time delay Δ t in signal edge.
Coil driver A103 is identical with coil driver B104, therefore coil driver
The signal edge opposed coil drive circuit A103 of B104 output equally exists time delay Δ t.
When input signal rising edge arrives, the signal of coil driver A103 output is first changed into high electricity
Flat, the signal of now coil driver B104 output is still low level；After elapsed time Δ t,
The signal of coil driver B104 output is changed into high level.Above procedure will form one by excitation wire
Circle 105 just (+) end flow to negative (-) current impulse held, the pulsewidth of this current impulse is Δ t.
Accordingly, when input signal trailing edge arrives, an intensity, pulsewidth will be formed identical, direction
Contrary current impulse.
Magnet exciting coil is passed through in the current impulse of different directions, exports magnetic field pulse signal 107.
When input signal 106 is in high level or low level steady statue, magnet exciting coil 105
Just (+) hold with negative (-) current potential held is identical, does not therefore have electric current to flow through coil, quiescent dissipation is approximately
Zero.
According to above procedure, circuit of the present invention possesses the function that level signal is converted to magnetic field pulse,
And significantly reduce quiescent dissipation.
