Low-power 12-bit 160-MS/s pipeline A/D converters are designed for wireless receivers. Instead of using ultra-deep submicron devices of low supply voltage, we employ analog-option devices that operate at supply voltage of 2.5V in a 90-㎚ CMOS process. To achieve lower power dissipation, an I/Q amplifier sharing technique is employed. Furthermore, charge transfer level shifters are proposed in S/H circuits and MDACs for realizing class-AB operation.
The area is 1.1㎟, the simulated power dissipation is 75㎽/channel and the simulated ENOB is 11.15bit.
