The voltage of several selections and determining resistance.Wherein the present embodiment does not limit the concrete type of diode and specific number.
Further, the present embodiment can be after the number and type for determining diode, and the sum of voltage of each diode is still
It is so unable to reach when requiring, increases a low resistance and divided.And the resistance value that the resistance is set in the present embodiment is very small,
Therefore, even if the signal of communication that imaging device provides fluctuates, the fluctuation of the partial pressure of the resistance will not be caused so that consumptive material
Chip can reach the process of modulation voltage amplitude.
Further, in this embodiment there are many series systems of each diode and resistance, the present embodiment does not limit this
It is fixed.Optionally, the resistance is connected on one end of arbitrary diode.
Specifically, resistance can be connected in series between each diode after the connection of each Diode series in the present embodiment,
Resistance can be also connected on to one end of each diode.The present embodiment does not limit the specific location of diode and resistance, only needs

The sum of branch pressure voltage of conducting voltage and resistance is second voltage, and the partial pressure of the forward conduction voltage of each diode and resistance is electric
The sum of pressure is less than first voltage.In this way, when each diode and resistance are linked into circuit, consumable chip is to imaging in the present embodiment
The second voltage of equipment transmission is just the sum of the branch pressure voltage of the forward conduction voltage and resistance of each diode, to complete consumptive material
The process that signal modulation is realized whether access that chip passes through each diode.
Further, no matter which kind of above-mentioned realization method is used, the type of the diode in the present embodiment in diode group
Can be a kind of or a variety of, the present embodiment does not limit this.Optionally, the diode is two pole of silicon diode and germanium

Pipe or multiple diode groups and low resistance replace original resistance.
It is assumed that the first level that consumable chip is transferred to imaging device is 5.4V, consumable chip is transferred to the of imaging device
Two level are 4.2V.
The first situation, if diode group all uses multiple silicon diodes, and the forward conduction voltage of single silicon diode
For 0.7V, then n=4.2/0.7=6 Diode series connection is needed.
The second situation, if diode group all uses multiple germanium diodes, and the forward conduction voltage of single germanium diode
For 0.3V, then n=4.2/0.3=14 Diode series connection is needed.
Further, in actual circuit, since the occurrence of second voltage is determined by imaging device, second voltage
It is too high or too low, the rule of communication of consumable chip and imaging device is all cannot achieve, the communication process of the two is also just cannot achieve,
Therefore, the present embodiment can select the larger diode of pressure drop as possible, can reduce the quantity of diode, especially be adopted in diode
With discrete component without being integrated into chip wafer in the case of, so as to cost-effective.
The third situation, if second voltage cannot just be divided exactly by the forward conduction voltage of conventional diode, this
Embodiment also can be used Diode series and the concatenated mode of low resistance, or using different forward conduction voltages diode into
Row combines to realize the forward conduction voltage of the diode group process equal with second voltage.
For example it is assumed that second voltage is 4.5V, according to the silicon diode that forward conduction voltage is 0.7V, then 4.5V/
The surplus of 0.3V more than 0.7=6, this 0.3V can be divided by connecting a resistance again, or connect a 0.3V again just
It is divided to the germanium diode of conduction voltage drop.
Wherein, when connect a resistance when, the resistance value of the resistance can according to the electric current for flowing through series diode group and
The voltage of 0.3V acquires.Assuming that the electric current for flowing through series diode group is 0.1A, then the resistance value of resistance is 0.3V/0.1A=3
Ohm.The diode and one 3 ohm of resistance that 6 0.7V forward conduction voltages can be used are connected, and can realize two
The voltage of the pole pipe group process equal with second voltage.And can be seen that the resistance value of resistance is very small, therefore even if electric current have it is micro-
Weak variation will not cause the wide fluctuations of partial pressure.Compared to the mode being only modulated with resistance, stability can be more
It is high.
Finally, in order to realize process that diode group has access to or is not linked into circuit, can lead in the present embodiment
Switch and the closure of controllable switch are crossed to realize, and in the present embodiment controllable switch type it is more, the present embodiment does not do this
It limits.Optionally, the controllable switch is any in relay, transistor and field-effect tube.
