A Formal Model of Identity Mixer Mixer

Identity Mixer is an anonymous credential system developed at IBM that allows users for instance to prove that they are over 18 years old without revealing their name or birthdate. This privacy-friendly technology is realized using zero-knowledge proofs. We describe a formal model of Identity Mixer that is well-suited for automated protocol verification tools in the spirit of black-box cryptogr...

IF Impedance and Mixer Gain of Hot-Electron Bolometers

We have measured the frequency dependent IF impedance and mixer conversion gain of a small area NbN hot-electron bolometer (HEB). The device used is a twin slot antenna coupled NbN HEB mixer with a bridge area of 1 μm x 0.15 μm, and a critical temperature of 8.3 K. In the experiment the local oscillator (LO) frequency was 1.300 THz, and the intermediate frequency (IF) 0.05-10 GHz. We find that ...

IF impedance and mixer gain of NbN hot electron bolometers

The intermediate frequency IF characteristics, the frequency dependent IF impedance, and the mixer conversion gain of a small area hot electron bolometer HEB have been measured and modeled. The device used is a twin slot antenna coupled NbN HEB mixer with a bridge area of 1 0.15 m2, and a critical temperature of 8.3 K. In the experiment the local oscillator frequency was 1.300 THz, and the IF 0...

New Mixer Design Notes

This mixer is based on a passive FET resistive frequency converter cell described by first described in the literature by Steven Maas [ ] and explored by Wes Hayward and others [ ]. One difficulty with a DFET passive mixer is obtaining negative gate bias. This has been achieved using gate conduction as in the TriQuint 5M31 [Campbell, Criss], a LO frequency driven negative voltage converter as i...
