A low-voltage low-power X-band cascode down-conversion mixer for wideband communication

Abstract

In this paper, a new wide-band low-voltage lowpower mixer is proposed. Using a modified stacked topology in conjunction with current bleeding technique, the mixer has a power consumption of 10mw while it uses a voltage supply of 1.2 V. Parallel peaking inductors are used to increase the RF frequency and broaden the bandwidth of the mixer. The 3-dB RF frequency band of the mixer is form 7GHz to 15GHz, which covers X-band completely, where its maximum power conversion gain is 10.6dB. The mixer has been simulated using 0.13µm CMOS technology model and results have been reported.
