EE479 Class Final Project High-Speed CMOS Operational Amplifier (Due Date: Monday, December 14, 2009, 6pm) 1. Introduction This purpose of the EE479 final project is to design a state-of-the-art Low-Voltage, Low- Power, High-Speed, High-Gain CMOS operational amplifier in the TSMC 180nm CMOS technology process that can be used in the Image Sensor Product. 2. Required Performance The following table summarizes the required performance for your designed final operational amplifier. Table 1: Final Operational Amplifier Target Performance Page 1 of 4

a. Input common-mode range of the project opamp is 1 V. The supply Vdd is 2V. If we have each current source and its cascade device stacked at the output, then the output swing is: Vss + 2 x Vds < Vout < Vdd - 2 x Vds. b. We design the Vdsat for each device to be equal to 150mV. c. To be in saturation, we have to have: Vds > Vdsat. Suppose we choose Vds=Vdsat+100mV. This way we have a good margin of 100mV into the saturation regions. In that case Vds=250mV
