LOW-POWER LOW-VOLTAGE VLSI OPERATIONAL-AMPLIFIER CELLS

VLSI operational amplifier cells that approach the physical limitation s of bandwidth, gain, and power consumption are described. To this pur pose, several HF compensation architectures are presented, such as par allel Miller, multipath nested Miller, and multipath hybrid nested Mil ler.VLSI operational amplifier cells that approach the physical limita tions of bandwidth, gain, and power consumption are described.
