| Title | The Design of a Rail-to-Rail Output swing using a Nested-Current-Mirror Single-Stage Amplifier with high PSRR. |
| Summary | The design of a nested-current-mirror (NCM) single-stage amplifier to advance its GBW-to power/area efficiency and CL drivability beyond the multi-stage designs, while preserving a rail-to-rail output swing. This design will be in the 55nm CMOS BCDlite technology, and should be able to work at 1.8V down to 1.2V power supply with 60 degrees phase margin, GBW of at least 10GHz (Closed Loop GBW, Closed loop gain of 20dB, bandwidth of 100MHz), open-loop gain of about 80dB, with an input-referred noise of about 500nV/sq.rt.Hz at 1kHz. The driving capability of the amplifier is for 2pF, and the total current consumption of below <120uA. The biasing is supplied through a constant Gm wide-swing cascode circuit such as to achieve a good PSRR for the entire design. Only if time permits, further improvement for a rail-to-rail input will be of interest and circuit layout for completeness with post layout simulations. Student is expected to use the Cadence EDA tools for circuit simulation in 55nm CMOS/BCDLite technology. This project is most suitable for student in the electronic option with specialization in IC Design with a good knowledge in analog circuits. |
