Abstract :
High-speed A/D converters (ADCs) are essential for improving the transfer rate of hard disk drives. This CMOS 6 b 500 MSample/s full-flash ADC for a read channel has 5.5 effective number of bits (ENOB) for a 125 MHz input signal (which is one quarter of the sampling rate). The ADC occupies 2.4 mm/sup 2/ and power consumption is 400 mW for a 3.3 V supply. 0.4 /spl mu/m CMOS technology is used.
