In this paper, a new image-reject low noise amplifier is designed for the 2.4 GHz industrial-scientific-medical (ISM) band. An inter-stage T-structure filter is used in the low noise amplifier design to provide 35-dB image rejection. The goal of this design is to merge the image-reject function into the low noise amplifier.
Two-phase micro-pipeline asynchronous modules show faster performance than common four-phase control systems, but the conventional systems with multi-port modules normally suffer from long signal paths on stacked C-elements. NOR-based control schemes provide an alternative solution to problems such as propagation delay. This paper compares modified versions… (More)
SUMMARY In the design of cascode CMOS low-noise amplifiers , the gate-drain capacitance is generally neglected because it is thought to be small enough compared to gate-source capac-itance. However, a careful examination will reveal the fact that the drain impedance of the input transistor significantly affects the input impedance through the gate-drain… (More)
