Koli K., Halonen K.A.I. CMOS Current Amplifiers: Speed versus Nonlinearity

Kluwer Academic Publishers, 2003. — X, 290 p. — ISBN 978-0-306-48003-4.CMOS Current Amplifiers: Speed versus Nonlinearity is intended as a current-amplifier cookbook containing an extensive review of different current amplifier topologies realisable with modern CMOS integration technologies. The seldom-discussed issue of high-frequency distortion performance is derived for all reviewed amplifier topologies using as simple and intuitive mathematical methods as possible. The topologies discussed are also useful as building blocks for high-performance voltage-mode amplifiers. So the reader can apply the discussed techniques to both voltage- and current-mode analogue integrated circuit design.
This book contains application examples with experimental results in three different fields: instrumentation amplifiers, continuous-time analogue filters and logarithmic amplifiers.Introduction to current-mode circuit techniques.
