Dynamic Offset Cancellation Techniques for Operational Amplifiers

At low frequencies, offset, 1/f noise and drift are the dominant error sources of operational amplifiers. This is especially true in CMOS technology. This chapter reviews precision techniques that can be used to achieve low 1/f noise and low offset in operational amplifiers. There are three types of CMOS offset cancellation techniques: trimming, chopping, and auto-zeroing. Trimming is usually p...

Equivalent Gain Analysis for Nonlinear Operational Amplifiers*

For low-voltage, low-power circuit design, the linear model for operational amplifiers is insufficient to accurately predict the static and dynamic behavior of the circuit. This paper introduces a nonlinear model for operational amplifiers based on amplifiers’ DC transfer characteristic. By using this nonlinear model, the behavior of an operational amplifier with feedback network can be describ...

Oscillators and Amplifiers for Various Applications

Ultrashort light pulses are nowadays used for a wide range of applications including metrology, communications, spectroscopy, terahertz science, ophthalmology, and material processing. Given this great diversity, it is not surprising that the required pulse parameters such as pulse energy and duration, repetition rate and wavelength are spread over a huge region of the multidimensional paramete...
