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 chip and a consumable container; a signal exchange circuit to carry out signal exchanging with the outside is arranged on a consumable chip substrate; a parasitic power circuit of electricity is acquired from the signal exchange circuit; a signal decoding circuit is decoded from the signal exchange circuit; the consumable chip also comprises a voltage stabilizing circuit between the signal exchange circuit and the parasitic power circuit; the voltage stabilizing circuit is provided with a voltage stabilizing diode; voltage pre-stabilizing is performed by making use of the characteristic that before inverse voltage of the voltage stabilizing diode is not broken down, voltages of the two ends of the voltage stabilizing diode are kept unchanged. The invention also provides a consumable container with the consumable chip. The consumable chip provided herein can effectively avoid influence upon input voltage of the parasitic power circuit during signal modulation, so that the sensitivity of the demodulating circuit is 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...
