A 0.6v Ultra Low Voltage Operational Amplifier

چکیده
A technique for low-voltage CMOS analog circuit design is presented in this paper. In this technique, voltage sources are added in series with the gates of the MOS transistors to lower the effective threshold voltages of the transistors. With the lowered effective threshold voltage, it is possible to build a host of analog circuit that operates with a decreased supply voltage. A 0.6V ultra-low voltage twostage operational amplifier (Op Amp) was designed in a standard 3.3V 0.35u CMOS process to validate the technique. Compared to its counterpart operating with a 3.3V power supply at a much higher power level, the lowvoltage Op Amp maintained the same gain-bandwidth product and most other key performance parameters.
