Switched-Capacitor DAC in 28nm FD-SOI

Type: Semester/Master project

 
Description:
A digital-to-analog (DAC) converter is a widely implemented circuit used to provide reference voltages. A DAC can be implemented with switched-capacitor circuits that do not consume static current. For this project, different implementations from the literature will be analyzed and compared. In addition, since the switched-capacitive DAC presents a regular structure, there is the possibility of defining an automated design flow for IP reuse.
 
Work distribution: 10% literature review, 50% circuit design, 20% layout design, 20% simulation and verification
 
Areas: DAC, switched-capacitive circuits, circuit design and simulation, CMOS 28nm FD-SOI

Design of a Charge Pump in CMOS 28nm FD-SOI for Wordline Boosting in Memories

Type: Semester/Master project

 
Description:
Voltage scaling represents a challenge when designing memory arrays. One of the techniques to ensure a robust write is wordline boosting. To this end, a charge pump is required to provide the required voltage and enough current capability.
