Abstract
An apparatus to sense the temperature of an ink-jet head includes at least one or more CMOS (complementary metal oxide semiconductor) lateral BJTs (bipolar junction transistors) to sense the temperature of the ink-jet head, and a current supply unit to supply a current to the CMOS lateral BJTs. Minimum sized CMOS lateral BJTs are applied to an ink-jet printer head so that precise temperature control can be performed in a shuttle or array type ink-jet printer.
