Abstract :
Circuit techniques for a CMOS amplifier suitable for read waveform signal processing in high-speed disk drives are described. A 30-MHz low-noise preamplifier with a gain of 100 was designed in 3-μm CMOS, capable of being driven by an inductive source, and producing an equivalent input noise voltage spectral density of 2 nV/√Hz. This, with other recent developments, makes it possible to conceive of entirely CMOS read/write signal-processing ICs
