Abstract

This thesis presents the design and implementation of a 5-V compatible operational amplifier in a 3.3-V technology capable of accepting rail-to-rail inputs, providing a rail-to-rail output swing and wide temperature range operation. The major system components consist of a fully-differential input (gain) stage and an output (driver) stage, with protection and bias circuitry components. The op amp is biased by a constant inversion coefficient current reference to optimize its performance over temperature. Measured results demonstrate the functionality of the design, which has been fabricated in a 0.35-µm, partially-depleted silicon-on-insulator (PDSOI) CMOS process.
