| Title | Design of a Bang-Bang or a hysteretic controlled DC-DC Buck Converter |
| Summary | In the DC-DC Buck Converter, a hysteresis comparator is used to compare a portion of the output voltage. There are two reference voltages, which are VH and VL. If the output is lower than reference voltage VL, then the charging switch is turned on to charge up the output voltage. When the output voltage rises above the reference voltage VH, then the discharging switch is turned on. The process repeats when the output voltage falls below again. The objective of this project is to design a hysteretic controlled DC-DC Buck Converter that operates with an input range of 2.5V down to 1.8V and produces a stable output voltage of 1.8V or lower, with a ripple voltage of no more than 5%. The converter should also deliver an output current of at least 100mA. Students are expected to use Cadence tools for circuit implementation and verification, and, if time permits, complete the layout physical implementation, including post-layout simulations. The design will be implemented using 55nm BCD-lite technology and is ideal for students specializing in IC design within the electronic option, with a solid background in analog circuits. |
