Design of Low-Power and High-Level-Integrated Switched-Opamp Circuits
Nowadays IC designers are constantly challenged not only with single-chip integration but also with low-voltage and low-power designs. This is motivated both by the increasing demand of low-voltage low-power IC designs from most market segments and by the reliability concern under voltage scaling of deep-submicron CMOS processes. While many low-voltage RF circuits [SHA 97, WAN 98, WON 02] have been able to operate at very low supply voltages, and recently low-voltage receiver front-end [UGA 01] has been demonstrated with special SIMOX/CMOS processes of low VT, the possibility of integrating 1-V channel-select filter and A/D converter in a CMOS process with high-VT is still unknown.
