A BiCMOS PreamplifiedWrite - driver IC for Tape Drive
نویسندگان
چکیده
A single-supply 5V preamplifier IC for magnetoresistive (MR) read element tape drive is described. The IC incorporates six independent read amplifiers, and four independent write drivers. The read amplifier is a fully differential current sense circuit. MR bias current direction steering is incorporated without additional switches in the signal path. In addition the IC incorporates a voltage reference, head diagnostics, control registers, and a serial interface. The entire IC, built in a 1.2pm BiCMOS process, occupies 36mm2. With a 39 Ohm read element the measured input referred noise is l.OnV/,,/Hz.
