摘要：

In this paper, input impedance characteristics of N-path filters is used to reject standard blockers at the input port of a receiver front-end. Due to using variable capacitors in the multiphase LO generator, the results of each performance parameter of the design shows a slight change in value at the whole of frequency range. The receiver NF is about 2.45dB at 1GHz switching frequency. The proposed receiver front-end is analyzed and is simulated at the schematic level using CMOS 90nm technology with a 1.5V supply voltage.
