✦ Synopsis
Nonideal factors which play a key role in performance and yield in high-precision operational amplifiers are rigorously investigated. Expressions for the offset voltage (V os ) and the common-mode rejection ratio (CMRR) are derived and correlated. The mismatch accuracy is analyzed for different transistor geometries in a CMOS OTA (operational transconductance amplifier) in 0.35 mm technology by using the Monte Carlo approach.
