High Conversion Gain Millimeter-Wave Monolithic IC Quadruple Subharmonic Mixer
Japanese Journal of Applied Physics, 2007We report a high conversion gain millimeter-wave monolithic IC (MMIC) quadruple subharmonic mixer adopting a novel cascode harmonic generator for an improved conversion gain. The proposed cascode harmonic generator produces 2.9 dB higher fourth harmonic output powers on the average compared with those of the conventional multiplier.

A High Conversion Gain Wideband Mixer Design for UWB Applications
2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019A CMOS mixer with wideband input impedance matching and high conversion gain is presented in this paper. Dual RLC circuits are utilized with Gilbert mixer for wideband input matching. Capacitive feedback, and inductive series and shunt peaking techniques, are used to implement the RF port matching network. Inductive peaking is also adopted to widen the

A high gain flatness high linearity down conversion mixer for Ku band application
2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011A high linearity down-conversion mixer for 12–18GHz Ku band application is presented in this paper. The proposed mixer based on Gilbert cell obtains high gain flatness. Bias current decoupling technique is adopted to suppress noise at the output. Current-injection circuit and resonating inductors at the source of switching stage are added to improve ...

A 60-GHz CMOS Down-Conversion Mixer with High Conversion Gain and Low Noise Figure
2018 16th IEEE International New Circuits and Systems Conference (NEWCAS), 2018In this paper, we present a 60-GHz single-balanced CMOS down-conversion mixer. The proposed mixer uses an on-chip active balun to furnish a differential output from an injected single-ended local oscillator (LO) signal. The millimeter-wave (mm-wave) active balun incorporates a cascode cross-coupled structure to generate the differential LO with a high ...

Nonlinear interferometry with high-gain parametric down-conversion
2021Interferometers have become essential devices within research and industry because they can measure phase shifts, often very small ones. Increasing the number of probing photons enhances the accuracy of this measurement, but with a bounded scaling called the shot-noise limit. The field of nonlinear interferometry studies how to surpass this limit using

A stability-ensuring procedure for designing high conversion-gain frequency doublers
1998 IEEE MTT-S International Microwave Symposium Digest (Cat. No.98CH36192), 2002This paper presents a new general procedure for designing optimum conversion gain class B FET frequency doublers. For the first time, the two key design variables, i.e. the reflection coefficients of the input and output matching networks, /spl Gamma//sub IMN,2fo/ and /spl Gamma//sub OMN,fo/, can be independently swept without risking device ...

Gaining turns and achieving high influence ranking in small conversational groups*
British Journal of Social Psychology, 1993Unacquainted subjects, in groups of four or five, viewed and then discussed a television programme on the topic of homosexuality. Afterwards, they ranked each group member in terms of how influential the member had been during the discussion. High‐ranking members, compared to low‐ranking members, had a greater proportion of aggregate speaking turns ...
