A V-BAND LOW-NOISE AMPLIFIER CO-DESIGNED WITH ESD NETWORK IN 65-nm RF CMOS

A V-band low-noise amplifier (LNA) with electrostatic discharge (ESD) protection using RF junction varactors is demonstrated in a 65-nm CMOS technology. The gate-source junction varactor is used to achieve a power-constrained simultaneous noise and input matching, and also as an auxiliary ESD protection for the NS and ND modes. The measured results shows an over 2.0-kV ESD protection in the PD ...

Integrated D-band transmitter and receiver for wireless data communication in 65 nm CMOS

A 140 GHz transmitter (Tx) and receiver (Rx) chip set has been developed in 65 nm CMOS by using on– off keying non-coherent modulation to support high speed proximity data communication. To the author’s best knowledge, it enables the first integrated multi-Gbps data link in D-band by saving power hungry frequency synthesizer, high speed data convertors and complicated digital signal processor. ...

Tunable beam shaping with a phased array acousto-optic modulator.

We demonstrate the generation of Bessel beams using an acousto-optic array based on a liquid filled cavity surrounded by a cylindrical multi-element ultrasound transducer array. Conversion of a Gaussian laser mode into a Bessel beam with tunable order and position is shown. Also higher-order Bessel beams up to the fourth order are successfully generated with experimental results very closely ma...

Optical beam forming for phased-array antennas

communications spectrum from copper cables, optical fibres, microwaves, radio and electromagnetic compatibility. Our research concentrates on optical signal processing and networks, mobile communications, microwave techniques and radiation from ICs and PCBs [1]. A considerable (and particularly interesting) part of it is related to optical beam forming for phased array antennas, using optical r...
