In this paper, a new wide-band low-voltage low-power 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,...
This paper presents a wideband low-noise mixer in CMOS 0.13-um technology that operates between 2–10.5 GHz. The mixer has a Gilbert cell configuration that employs broadband low-noise transconductors designed using the negative-positive feedback technique used in low-noise amplifier designs. This method allows broadband input matching. The current-bleeding technique is also used so that a high conversion...
In this paper, a new distributed active mixer is presented. The scheme is based on the conventional Gilbert-cell multiplier with complementary transconductance stage. By adding the preamplifier and non-uniform artificial transmission lines on the topology, the new distributed active mixer is obtained. Comparison of the new mixer with the topology in absence of preamplifier shows that it has higher...
