Abstract
This paper reviews architectural and circuit design considerations
for realization of low power dissipation in high-speed
CMOS A/D converters. Basic limitations on achievable
power dissipation in MOS samplers and quantizers is first discussed.
Then a number of practical design aspects are illustrated
with discussion of a 10-bit, 20-Msample/s pipeline A/D
converter[1] implemented in 1.2-µm CMOS technology
which achieves a power dissipation of 35 mW at full speed
operation on a 3.3V power supply. |
