Preamplifier analysis for low-noise CMOS instruments amplifier by using mentor graphics / Mahanijah Md. Kamal

This thesis presents a partial fulfilment of the requirement for the Bachelor of Electrical Engineering program and titled "Preamplifier analysis for low-noise CMOS instrumentation amplifier by using Mentor Graphics". This project was taken from IEEE Journal Solid- State Circuits, vol 32, no. 7, July 1997 (1] where the performance of preamplifier circuit is being analyzed. The preamplifier circuit is part of the CMOS instrumentation amplifier. The circuit has its requirement that must be observed. The circuit is first drawn in Design Architect ( DA ) where all the rules and regulation for the electrical codes are obeyed. ACCUSIM is used to simulate the circuit. The circuit has been analyzed using 1.2-µm n-well CMOS process. A CMRR is less than 70dB. The total power consumption for this circuit is 1.4163mW.
