Operational Amplifiers (op-amps) are one of the most commonly used blocks in analog and mixed signal VLSI design. Designers often spend considerable time in designing op-amps analytically, and then realize that the simulated circuits do not match with analytical expectations. This is primarily due to modeling of short channel MOS devices using long channel equations. Finally an adhoc mechanism is adopted to realize the op-amp with the help of a simulator. Proposed Potential Distribution Method… CONTINUE READING
