Design Criteria for Low Distortion in Feedback Opamp Circuits (The Springer International Series in Engineering and Computer Science (720))

Broadband opamps for multi-channel communication systems have strong demands on linearity performance. 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 behaviour of such circuits and this is the main subject of Design Criteria for Low Distortion in Feedback Opamp Circuits. The biasing of each transistor in the circuit is a major issue and is addressed in this work. It is important to bias the transistor such that the distortion is low and stable in the entire range of its terminal voltages. This will ensure high linearity and robustness against variations in circuit conditions such as power supply voltage, bias current and process variations. Design Criteria for Low Distortion in Feedback Opamp Circuits is written for.

provides An Example Of How To Use The Phasor Method In The Analysis Of Distortion In Analog Circuits Such As Operational Amplifiers. The Authors, Both Associated With The Physical Electronics Department At The Norwegian University Of Science And Technology, Trondheim, Norway, Demonstrate The Benefits Of The Miller Opamp With Folded-cascode At The Input For High Speed And Low Distortion. Also Explored Are The Non- Linear Coefficients Versus Frequency. The Slopes Of The Distortion Versus Input Amplitudes And Versus Frequencies Are Predicted By Means Of Hand Calculations And Verified By Means Of Simulations And Experimental Data Is Added. Suitable For Both Novice Designers And Experts In The Field Of Analog Cmos Design. Lacks A Subject Index. Annotation ©2003 Book News, Inc., Portland, Or
