Design of variable gain amplifier in CMOS technology

in partial fulfillment of the requirement for the degree of Doctor of Philosophy 2015 i with gate peaking technique.Measurement results show that the proposed cell-based design method is not only feasible, but also achieved very good performance in terms of accuracy, bandwidth, power consumption and die area.The body-tuned reconfigurable VGA can also work as a tunable PGA with variable gain step, which demonstrated the re-configurability, power scalability and versatility of the proposed cell-based design method.
