Owing to its well-known properties of possible power-noise match as well as superior noise performance, the inductively-degenerated low-noise amplifier is nowadays the most-widely used RF preamplifier topology. However, there is not much flexibility when setting the amplifier’s input impedance to match the source impedance, as for a given biasing condition, matching is achievable only for a par...

Noise equivalent power and time constant of a submillimeter wave hotelectron bolometer (HEB) made from monolayer graphene are analyzed using the lowest electron-phonon thermal conductance data reported to date. Frequency-domain multiplexed JohnsonNoiseThermometry (JNT) is used for the detector readout. Planar microantennas or waveguides can provide efficient coupling of the graphene microdevice...

Abstract This paper presents an analysis for a multi-stage Low Noise Amplifier (LNA) application on deep brain stimulation. A low noise amplifier with high gain, moderate bandwidth and reduced is designed simulated using LT Spice PTM BSIM4 CMOS models. The novel LNA circuit topology proposed which uses cascaded style to improve mid-band gain of LNA. achieves margin ranges between 60-67 (dB), 2X...

A noise reduction input matching technique for broadband low noise amplifiers (LNAs) is presented. The proposed LNA employs a positive active feedback network besides of the conventional common-gate (CG) amplifier to achieve both wideband input signal matching and low noise figure (NF), simultaneously. Compared to the conventional broadband noise cancellation techniques, the presented approach ...

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...
