Application of Circuit Synthesis to the Design of A Three-Stage 4 MHz to 7 GHz Amplifier for a Wide Band Fiber Optics Receiver

In fibre optic very high datarate systems it is necessary to have a ultra large band high gain low noise amplifier after the front-end. The purpose of this paper is to show how powerful analytical techniques, such as the real frequency technique, may be applied to the design of a 4 MHz - 7 GHz amplifier. A two stage monolithic amplifier designed according to the theory gives 17 dB gain and a 3 stage hybrid amplifier 16 dB gain accross the band.
