Beschreibung
Zusammenfassung:	An ink cartridge for an ink jet printer comprises a cartridge body and an integrated chip-type sensing circuit disposed on the cartridge body. The sensing circuit comprises a low-voltage linear regulator (1), a reference voltage generator (2), a programmable oscillator (3), a sine-wave generator (4) and a low-frequency isolation module (5). When being applied to an ink jet printer, the sensing circuit of the present invention can automatically produce excitation responses with specific resonant frequency characteristics and charge-discharge impedance characteristics which can be recognized by the printer according to excitation signals of the ink jet printer, thereby achieving precise matching with the ink jet printer. In addition, the sensing circuit of the present invention does not need any external power supply; the high integration of the sensing circuit effectively reduces the use of external components and the area of a printed circuit board, thereby effectively reducing the cost.
