When these opamps are integrated in deep sub-micron CMOS technologies, the signal-swing has to occupy a large part of the rather low supply voltage to maintain the signal-to-noise-ratio. To obtain opamps with low distortion it is necessary to do a thorough analysis of the nonlinear ...

Current Feedback Amplifiers Current Feedback Amplifiers In their effort to approximate the ideal op amp, manufacturers must not only maximize the open-loop gain and minimize input-referred errors such as offset voltage, bias current, and noise, but must also ensure adequate band-width and settling...
A circuit method that is very important for linear amplifiers is called feedback. Feedback means taking a fraction of the output wave of an amplifier and connecting it to the input. This fed-back signal can be connected so that it either adds to the normal input or subtracts from it (Fi...
relaxation oscillators are simpler and less sensitive. This explains the growing interest in designing relaxation oscillations using operational amplifiers, operational transconductance amplifiers, second-generation current-conveyors and current feedback operational amplifiers (CFOAs). Of particular interest here ...

A differential amplifier having a pair of negative feedback amplifiers serially connected in mirror symmetric fashion, each of said negative feedback amplifiers comprising: an input stage including an input terminal to which an input signal is applied, an output terminal producing an output signal...
