چکیده:

This paper describes a 4-bit 4GS/s Jlash analog to digital converter for Direct-Sequence IJLI/B applications, using a 0.l8pm CTIOS technologt. The converter utilizes full custom logic, low noise preamplifiers, and fast compar(7tors with inductiveloads. The analog and digital power supplies are I8V and 2.2V, respectively,a nd the power dissipation is only 68-mlt. The dffirential input *ving is IVpp at 1 8-V supply. Simulatederformance for 4GS/s shows 22.23 dB of SNDR at 1.5-GHz input frequency. The INL is -0.31/0.35 LSB, andthe DNL is -0 18/0.25 LSB.
