Problems solved by technology

If the parasitic power supply circuit 10 overcompensates, it will cause the modulation signal obtained by the demodulation circuit 20 to be wrong, and when the sensitivity of the modulation circuit is very high, this effect cannot be ignored, which seriously affects the improvement of the sensitivity of the radio frequency consumable chip

Abstract

The invention provides a consumable material chip and a consumable material container. The consumable material chip substrate is provided with a signal exchange circuit for exchanging signals with the outside; a parasitic power supply circuit for obtaining electric energy from the signal exchange circuit; A demodulation circuit for demodulating signals; the chip also includes a voltage stabilizing circuit between the signal exchange circuit and the parasitic power supply circuit, and the voltage stabilizing circuit is provided with a voltage stabilizing diode. Before the reverse voltage of the Zener diode breaks down, the voltage at both ends of the diode is basically unchanged, and the pre-stabilization is carried out. The present invention also provides a consumable material container having the above-mentioned consumable material chip. The consumable chip provided by the invention can effectively avoid the influence on the input voltage of the parasitic power supply circuit when modulating the signal, so that the sensitivity of the demodulation circuit can be higher.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to a consumable container used in a printer and a consumable chip used in the consumable container. Background technique [0002] Toner cartridge is a common laser printing consumable, widely used in laser printers. Most of the existing toner cartridges are provided with a chip, and the chip usually stores information such as the model of the toner cartridge, the model of the applicable laser printer, and the remaining amount of toner in the toner cartridge. Whenever the toner cartridge is installed on the laser printer, the laser printer will read the above information from the chip to determine whether the toner cartridge is suitable for the laser printer. [0003] The chip of some existing toner cartridges is a non-contact chip, that is, the communication between the chip and the laser printer is realized through radio frequency technology (RFID). The circuit block diagram o...
