Abstract

This thesis presents a fully differential operational transconductance amplifier (OTA) for very low voltage and fast settling application implemented in TSMC 0.25 µm Complementary Metal Oxide Semiconductor (CMOS) process technology. The design employs full custom design approach in which the design starts with design specification determination followed by simulation for characterization purpose and validation. The layout design for the OTA is achieved along with the post layout simulation and layout verification. The layout is designed based on TSMC 0.25µm CMOS process technology and design rules. The performance analysis and the layout design of the OTA are done by using Mentor Graphics software. The OTA consists of three main circuits; hybrid class A/AB OTA, common mode feedback (CMFB) and biasing circuit. The two stage OTA is proposed to satisfy the high DC gain requirement for high speed application. The performance analyses are compared to three different temperatures which are 70 degrees (worst-case), 25 degrees (typicalcase) and 0 degree (best-case).
