Abstract :
Two amplifiers designed with z domain technique are presented in this paper. The first amplifier is featured with frequency response of elliptic equation, which has the defined operating band from 1.8GHz to 2.7GHz. The second amplifier is a dual-level amplifier which is designed with the aid of Yule-Walker scheme. This amplifier shows a 3-dB difference in amplitude response in the operating band. The design of both amplifiers demonstrates the advantages of z-domain technique and Yule-Walker scheme, which leads us to define complex frequency response of an amplifier arbitrarily. The amplifier characteristics including S parameter, 1-dB gain compression point (P1dB), and noise figure are measured and discussed in the paper.
