A novel frequency compensation technique for three-stage amplifiers is introduced. The proposed solution exploits two Miller capacitors, two resistors and an additional feedforward stage which can be implemented without entailing extra transistors. Design equations using the phase margin as design parameter are carried out. The technique is used to design, with a standard CMOS 0.35-mum process, a 2-V three-stage amplifier driving a 500-pF load capacitor. The amplifier dissipates only 70muA at… CONTINUE READING
