Logarithmic Amplifiers and Their Integration

With the development of modern radars, communication, remote control and laser ranging technologies, the logarithmic amplifier is in great demand. Performances and features of the logarithmic amplifier are described, along with its operational principles.Major types of the log amplifier and their theory of operation are discussed. The development of log amplifiers abroad is examined. Some of the integrated log amplifiers in our country are introduced.
