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,...
A new configuration of wideband bandpass filter (BPF) with notched bands is presented. Proposed BPF is based on stepped-impedance resonator. By utilizing dual stepped-impedance resonators in folded topology a rectangular-ring resonator is formed. Two notched bands in the passband are achieved without using asymmetrical coupled lines. In other words, the filter configuration is capable of producing...
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...
