Abstract :
A frequency compensation technique for three- stage amplifiers is introduced. The proposed solution exploits only one Miller capacitor and a resistor in the compensation network. The straightness of the technique is used to design, using a standard CMOS 0.35-mum process, a 1.5-V OTA driving a 150-pF load capacitor. The dc current consumption is about 14 muA at DC and a 1.6-MHz gain-bandwidth product is obtained, providing significant improvement in both MHz-pF/mA and (V/mus)-pF/mA performance parameters.
