Technical field
The invention belongs to electronic circuit technology field, relate to a kind of circuit level signal being converted to pulsed magnetic field.
Background technology
For the equipment utilizing magnetic field to carry out data communication, as magnetoelectricity signal isolation coupling device, Implanted cardiac pacemaker communication system etc., needing transform electrical signals in its course of work is magnetic signal, then is detected by magneto sensor and be read circuit collection, thus realizes Signal transmissions.This wherein, " level-magnetic field " change-over circuit is an indispensable component units.Existing scheme is that field signal is directly corresponding with level signal, such as: export field signal during high level, without field signal during low level; Or export forward field signal during high level, during low level, export opposing magnetic field signal.All there is long-term electric current by magnet exciting coil in above scheme, thus there is higher quiescent dissipation, is difficult to be applied to low-power consumption portable equipment.
Summary of the invention
The present invention is directed to the deficiency that existing " level-magnetic field " change-over circuit exists, provide a kind of circuit arrangement level signal being converted to pulsed magnetic field, the program significantly can reduce the quiescent dissipation of circuit.
The technical scheme that technical solution problem of the present invention is taked is:
Level signal is converted to a circuit for 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, shakes for suppressing input signal.

Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Device level signal being converted to pulsed magnetic field of the present invention as shown in Figure 1.This circuit is by Anti-shaking circuit 101, and delay circuit 102, coil driver A103, coil driver B104 tetra-electronic circuits and magnet exciting coil 105 5 part form.
Anti-shaking circuit 101 receives input signal 106, the inhibit feature to signal jitter possessed by it, the adverse effect that erasure signal self or the burr caused by external disturbance produce subsequent conditioning circuit.
Anti-shaking circuit 101 exports two identical signals, one of them signal direct input coil drive circuit A103, and another signal is first by delay circuit 102, then input coil drive circuit B104.Therefore, there is a specific time delay Δ t relative to the signal edge of input coil drive circuit A103 in the signal edge of input coil drive circuit B104.
Coil driver A103 is identical with coil driver B104, and the signal edge opposed coil drive circuit A103 that therefore coil driver B104 exports exists time delay Δ t equally.
When input signal rising edge arrives, the signal that coil driver A103 exports first changes high level into, and the signal that now coil driver B104 exports is still low level; After elapsed time Δ t, the signal that coil driver B104 exports changes high level into.Above process by formation one by magnet exciting coil 105 just (+) hold and flow to the current impulse of negative (-) end, the pulsewidth of this current impulse is Δ t.
Accordingly, when input signal trailing edge arrives, formation intensity, pulsewidth is identical, the current impulse that direction is contrary.
The current impulse of different directions, by magnet exciting coil, exports magnetic field pulse 107 signal.
When input signal 106 is in high level or low level stable state, just (+) end of magnet exciting coil 105 is identical with the current potential of negative (-) end, and so there is no electric current and flow through coil, quiescent dissipation is approximately zero.
According to above process, circuit of the present invention possesses function level signal being converted to magnetic field pulse, and significantly reduces quiescent dissipation.
