This paper presents a current re-use quadrature front end receiver architecture for ISM Band. The proposed architecture is a stacked QLMV cell which consists of a low-noise amplifier (LNA), mixer and voltage-controlled oscillator (VCO), which feeds into the intermediate frequency (IF) load. The LNA is a common source amplifier with Ls source degeneration, a double-balanced Gilbert cell mixer an...

An analytic technique and figureof-merit (Fnm) for the trade-off of noise measure and mismatch loss in the design of low noise amplifier is presented.

There is a strong interest in the Submillimeter community to increase the IF bandwidth of SIS receivers in order to facilitate extra-galactic astronomy. However, increasing the IF bandwidth generally also means increasing the IF operating frequency of the mixer, because it is very difficult to achieve a good IF impedance match to a low noise amplifier (LNA) for more than an octave bandwidth. Co...

The manufacturing of intravascular imaging coils poses several challenges. Due to their size, it can be difficult to incorporate local matching networks and signal amplifiers.
