Abstract
This chapter deals with the concept of first time right IC. A development of subsystems for wireless application is used as test case. The subsystems are Low Noise Amplifier (LNA), Medium Power Amplifier (MPA) and Variable Signal Generator (VSG). Several issues such as suitable multiband design flow and high speed switch must be solved. A new design methodology of integrated circuits for multiband application is presented. The design methodology is modified from a typical Monolithic Microwave Integrated Circuit (MMIC) flow. Core based design, parasitic aware approach and power constrained optimization are introduced into the new design flow. The same core circuit topology is used as main block to design 2.4 GHz and 3.5 GHz LNA and MPA. A power constrained optimization is applied to a test case amplifier i.e. broadband amplifier to get the optimized RF performance. The optimization is simulation-based technique. A 0.15 µm 85 GHz PHEMT is used in designing the LNA, MPA and broadband amplifier. This chapter also introduces the inventions of Voltage Controlled Oscillator (VCO), Mixer, Low Noise Amplifiers (LNA), Power Amplifiers (PA) and Transmit-Receive Switch (T/R). These circuits are crucial components for RF and Microwave front-end integrated circuits. The elements of inventions of circuits are clearly explained. The inventions reflect the requirement or the need of solving current problem using available technology.
